Ordering fake eyes

I'm studying for another test I have on Monday all about contact lenses and prosthetic eyes. Prosthetic eyes are actually really cool. One thing they have to consider when ordering a fake eye is his big to draw the pupil (the black part of your eye). A real pupil can change size a lot in different lighting and when you're talking or reading. The doctor will base the pupil size off of the good eye's pupil size in normal room illumination and in conversation so that the eyes will look normal when they're talking with someone. How cool is that?

Vision therapy

I had my vision therapy test today. I had no idea before I started school that optometrists even offer vision therapy services. What is vision therapy, you may ask? It's to help you out when you have a hard time controlling your eyes. For instance, you can have a hard time turning your eyes in or crossing you eyes, which makes reading especially hard. Or you can have a hard time focusing your eyes. About 5% of the population has some form of visual dysfunction, but many people with binocular vision problems think their eyes are like everine elses, so they never think to get therapy.
The best part is that with the help of therapy about 85-90% of people have a lot of improvement. This is especially true with children. Sometimes children with reading problems actually don't have problems with reading; it's more with their eye movements and focusing abilities.

Anyway, so that's what my test was on this morning. Now I've got to go study for my test on children's vision screenings, which is tomorrow.

City planning

For many many years, I have loved the idea of planning out cities. When I was 11 or 12 I would spend hours in my room drawing maps of islands with different terrains and climates and label different cities and what their exports and imports would be. I know, I was super cool. This fascination has never really left me, and was further made evident by be checking out this book from the library last week:

It's a story of a fictional Roman city, starting at it's inception as a military outpost and ended, well, I'm not sure how it ends because I haven't finished it yet. But it is really cool. I love stuff like this. 

Tornado warnings

The tornado sirens went off this evening for the first time since we moved to Columbus. We had a tornado warning issued for about thirty minutes, so we got Olivia out of bed, Katie grabbed the flashlight, and we headed to the basement. It's kind of spooky to hear the wail of the tornado siren along with the pounding rain and wind. But Olivia fell asleep on the carpet in our basement, and Katie and I played a boggle-like game together, so it was actually a little bit cozy. And then after the storm passed we came upstairs and finished washing the dishes, as if nothing happened. Kind of weird how the storms here pass so quickly.

Ender's Game

Katie and I watched Ender's Game with some friends at a REAL movie theater tonight. It was our first official date in many months, I think (if you don't count temple trips). I really wanted to like it, but I think that since I first read the book when I was 14, and have re-read it 3 or 4 times, I couldn't help but notice changes from the story. Granted, I think they did a very good job given the limited parameters of the movie format. I would have probably liked it more if I hadn't read the book, but then again maybe the movie wouldn't have made any sense. 

LemonLyman

After watching West Wing this evening with Katie, I found that this exists:

lemonylyman.tumblr.com

And it looks like a pretty active site.

From the header:

Josh has fans. Not many of them from the looks of it, but what we lack in numbers, we more than make up for in fervor.

Rules: Don't post in the wrong place. Stay on topic, people. Don't use capital letters. I don't have time to tell you twice.

Extreme patients

Notice that I did not write "extreme patience." That is something I do not have. But I do have a lot of extreme and crazy patients at my clinic.
Today, for example, was wacko. They guy I saw was mentally handicapped and had severe behavioral problems. At the end of the exam, he didn't know that he had a $2 co-pay, and he FLIPPED OUT at the check-out counter. He refused to pay the $2 co-pay, and proceeded to make a huge scene by yelling, storming about, and stomping very fast down the hallway. It kind of reminded me of Olivia throwing a tantrum, except this guy was 6' 2" and weighed about 210 lbs.
It seems like any crazy patients that come to the school are always seen by me. And I'm not the only one who thinks so: everyone at the front desk and the Eyewear Gallery agrees that all the special situations seem to happen when I'm around. The main secretary at the Eyewear Gallery gave me a piece of gum as a reward for handling the situation nicely.

Mission journal

Katie and I have been putting together David's Christmas package, and I thought I would write a quick letter to go along with the things we got him. I pulled out my mission journal for the first time since my mission to get some inspiration about mission related things. I'm not sure why I hadn't looked at it before. When I started reading the passages that I wrote over 8 years ago, I felt like I was immediately back on the streets of Switzerland. It was weird. I would take a break from reading and look around our living room and realize how nice my life is right now, then I would read some more about what my day to day life was like.

Two things stood out to me while reading my journal:

1. How depressing my life should have been, if an outsider was observing my day-to-day actions
2. How upbeat I was when recounting these events in my personal journal

Sure, I had some days where I wrote about how depressed I was and stuff, but most days were things like "Today was awesome! We did street contacting for about 3 hours then knocked on people's doors for the rest of the evening, and we found two people who said that we might be able to come back sometime!" And this was in February, where the sun set at 4:30 PM and we had to be out until 9:00 PM. 

Anyway, I am very grateful for my nice, easy life now. And I am also grateful that I could experience a mission so that I cold learn the value of hard work and how to turn to the Lord for motivation and comfort. 

Dollhouse

Katie and I have been busy making a dollhouse for Olivia for Christmas. It's super sweet, and I think Olivia is going to love it. Katie bought the basic shell of the dollhouse at Goodwill for like $4, and we've been upgrading it since then. I got some simple LED lights that have a switch by the door so that the home can be lit up on all three levels. Here's a picture of the house with the light's on:

It's kind of a terrible picture, but just imagine it being super charming, because that's what it looks like.

We also bought some wood scraps from Home Depot and have been making furniture, such as two twin beds, a queen sized bed, a kitchen table, and a fridge. Katie also found some sweet doll house furniture at the thrift store the other day, so that got us some arm chairs, a few vanities, and coffee table, and some other cool stuff.

A terrible joke

A few months ago I woke up in the middle of the night because I thought of a really good joke. I quickly wrote it down then fell back asleep. In the morning I read what I wrote, and it's pretty terrible. I thought I'd share it with you all because, well, I can't think of anything else to write about right now, and you already know what a terrible person I am. So here it goes:

What do you call a kid with a speech impediment who loves to draw?

Autistic

Sometimes I feel like a horrible person

Like today, for instance. We had Stake Conference, which was great. It was held at the Stake center, but was web-casted to the other buildings in the stake. I think someone forgot to check the microphones for the choir. One of the microphones was right next to a sweet brother, who, bless his soul, couldn't carry a tune if his life depended on it. He was kind of drowning out everyone else in the choir. And the worst part is that I couldn't stop laughing, no matter how hard I tried. I was plugging my nose and biting my tongue so hard that I had faint hint of blood in my mouth. I finally resorted to covering my entire face while leaning over so that perhaps people would think I was crying instead of laughing, though I doubt I was fooling anybody. Whenever I would get myself under control, I would hear his warbling voice and start the vicious cycle over again. Even now I can't even stop myself from laughing from thinking about it.

Fake MRI

This is a picture of a fake MRI machine. The story behind it is that some researchers studying autism were having a hard time getting imaging of austistic kids, so they hired some people to recreate a life-sized model for the kids to get used to before they have to do the real thing. I think it's a very creative, thoughtful, and sweet thing to do.  I read about it here: http://hackaday.com/2013/11/09/full-size-mri-machine-replica/

Exercise

I have been pretty good about exercising lately, and I feel pretty good about it. I've been riding our exercise bike every night this week, and my bum hurts. It hurts pretty bad. Hopefully I get bums of steel pretty soon.

Also tonight Katie and I played "Upwords" on the couch. I will there were more board games that can be played on the couch. I've done lots of searches in the past to look for games that can fall in this category, and it seems like only Battleship and Yamslam work. Anyone else have any ideas about what kind of board games can be played easily on the couch?

Productive evening

Sometimes my evenings feel awesome, and it's usually because I have tons of energy after exercising. Here is a rundown of how productive I have been:

• Rode the exercise bike for 30 minutes,
• while lifting weights.
• Started a load of laundry,
• folded that load of laundry,
• and folded the load of clean laundry from a week ago that hadn't been folded yet.
• Took a shower.
• Washed dishes from dinner.
• Swept the floor.
• Paid bills online.
• And wrote on my blog.

Bam!

Explaining c-sections

Olivia asked us this evening how Felix will get out of Mommy's tummy. We explained that most children come out a special, different way, but Felix will need help from the doctor to get out. This piqued her 4-year-old curiosity and naturally wanted to know more. I can't really remember the whole conversation, but here are the highlights:

• The doctor uses a sharp knife to cut her tummy. Olivia asked if she will cut it in half or in quarters, and we said just just one cut.
• This cut wont hurt Mommy because she will get special medicine. 
• The doctor will take baby Felix out of Mommy's tummy, then she will sew her back up using a needle and thread. This also wont hurt Mommy.

Once we explained the stitches, she started laughing and said, "That's really silly!" And when you think about it, it does seem a little silly.

Duette lenses

One thing I love about being an optometry student is that I can try out a bunch of different contact lenses for free. I guess their reasoning is that I'll have first hand experience to know what to recommend to patients. Today I got a free pair of Duette lenses, which are pretty neat. They are a hard contact lens in the middle with a soft contact lens "skirt" around it so you get the benefit of the crisp vision that corrects astigmatism with the hard lens and the comfort of the soft lens skirt. They also last 6 months long per pair, so I just got 6 month's worth of lenses for free. Sweet! I think I like them. They definitely feel different from soft lenses, but it's not bad. The thing is I don't have astigmatism, so my vision is the same whether I wear these or not, but I'm not complaining.

I also think it's pretty cool to know so much about eyes, because I can answer a lot of people's questions about eyes. I had my first physical today since probably my mission, and the doctor who gave me the exam asked me a bunch of questions about her eyes, like if it's OK for her to wear to left-eye contact lenses since she ran out of right-eye contact lenses (the answer: probably not, in case you're wondering). 

Comfy couch

We drove down to IKEA a week or so ago and got a new couch! I am in love. I love that there is a hide a bed thing that pulls out and that its SO EASY to pull out. I love that we can all sit in it together and lay back without kicking each other. 

It's the baste.

We're breaking it in now so that guests can sleep on it without it killing backs. The couch isn't a soft as the one at the store, but I think that's because there aren't hundreds of people trying it out everyday.

Fiver and Hazel

I finished reading "Watership Down" a few months ago, and I highly recommend it. I thought it would be fun to tell Olivia stories about the main characters from the book (rabbits named Fiver and Hazel), to introduce her to the characters so that when she reads the book someday, she would already have some vague memory of them. I tried to incorporate their personalities in the stories too. Here are some stories I've made up including these characters:

• Fiver and Hazel reach a river and need to cross it, and Fiver had the idea to build motorcycles. They go the library and check out a book on "How to build motorcycles" and Hazel builds the motorcycles for them. Then they do "popawheelies" over the river.

• Fiver's mommy tells them to gather berries, so they go to the forest to get them. Fiver notices that the red berries are good, but the black berries will make you sick. Fiver tells Hazel not to eat the black ones, but he doesn't listen and eats a black one and gets really sick. Fiver runs home to get his mommy, and she gives him some medicine and gets better. (Olivia got really scared in this one, and requested a happier story after I told it.)

• They eat blue carrots and turn blue. The only way to turn normal is to climb to the top of a high mountain and do back-flips all the way down. 

• They go to the beach and build a massive city in the sand and live there for a few days, each bunny taking turns playing different roles, like police officer, teacher, grocer, and bus driver.

The funny thing is that Olivia has requested a "Fiver and Hazel" every single night since I first started telling them back in the beginning of September. And she knows whenever I try to repeat a story.

I'm studying tonight, so you get palindromes

I've got a midterm on Monday in my Clinical Medicine course, and I don't like studying on Sunday, so I'm trying to study everything tonight. But I'll still probably have to wake up early on Monday.

Anyway, I thought I would tell you some palindromes I made up. After reading "Poisonwood Bible," I've always tried to pay attention to palindromes. Let me tell you, they are hard to make up. I'm always impressed when I hear someone say one. So here's what I've got:

Doing Dishes
Pots... pans. I snap, stop.

Petting zoo rule #1
Step on no pets

Yeah, that's about it. Do you know any others?

I won candy

Today was my first day of Friday afternoon clinic. I had heard Fridays are pretty rough because its always super busy. My theory is everyone wants to take off work Friday afternoon to get their eyes checked so their weekend starts early.

Anyway, when my second patient arrived I looked at his medical record and wondering why he was even here. His eyes were perfect. He needed no glasses. No eye problems. No health risks. 

I mentioned this to my new attending, and she said, "If you can finish the entire exam in less than 60 minutes, I'll bring candy for you and every else."

Nothing motivates me more than a challenge involving candy. A typical exam that we give at the college takes 90 minutes. They've been pushing us to get faster since day one. We originally had 4 hours for the exam. Then two hours. Now 90 minutes. When were practicing in the real world, we'll have anywhere from 30 minutes to 10 minutes for each exam. 

How fast did I go? 50 minutes. Bam! New record! My attending was impressed. And I'm getting candy next week.

Oh, and the reason he came in for the exam in the first place: he wanted some stylish glasses frames, and wanted to see of any prescription was needed. He needed a little bit, not much. He was pretty happy.

Conversation with Olivia

I had a really funny conversation with Olivia last night. As I was tucking her in, she asked me, "Daddy, how did baby Felix get in mommy's tummy?"

Great. How am I going to explain this?

"Well, babies come to a mommy and a daddy and the baby comes down from heaven."

She was quiet for a while and then said, "Do babies ever fall down from heaven?"

"No, babies are very safe in heaven. They won't fall down to earth."

She was quiet again for a while, then said, "Are my babies waiting in heaven now for me?"

"Yeah they're waiting for you now, and they'll come when you are older and married."

"I think they'll have to wait for a long long time...do you think they'll be bored up there?"

"I don't think so. I bet there is fun stuff to do."

"I bet baby Felix is pretty bored in mommy's tummy. Probably he will want to play with me a lot when he comes out."

"Probably."

Then she really impressed me with her insight and planning.

"Daddy, when I'm a mommy and have my babies, I think when I go to the temple on a date, I can have my babies watch baby Felix because he will be too little to go to the temple."

"That's a good idea Olivia."

I am always impressed with her ability to connect the dots. Sometimes she seems so much older than just four years old.

My patient today

I had a life-changing patient today.

She told me main purpose of her exam was to get glasses so that she could read and try to enjoy her life a little bit, because she wasn't planning on living longer than another four to five years. She had almost every problem known to man. When I picked her up, she was in a motorized wheel chair. She wasn't old (only 55), but she has suffered from seizures almost daily since she was two years old. This has severely impaired her walking ability.

She had breast cancer (with bilateral mastectomy -- she lifted her shirt and showed me the scars, which was shocking). She had colon cancer, and had almost all of her bowels removed, and uses a colostomy bag. She has lung cancer, from smoking every day. She has type 1 diabetes (the one you're born with). She has skin thinning, thrush in her mouth, yeast infections, incontinence, migraines, extremely low blood pressure, three heart attacks, a pace maker, 2 strokes, depression, and suicidal thoughts.

We had a long talk about suicide. That was interesting. Eventually, she said she doesn't want to take her life, but she is very ready to go. She is DNR, which means "do not resuscitate," so if she ever passes out or needs treatment or CPR or a blood transfusion or something, she doesn't want any help and she wants nature to take its course.

During the exam, I did her refraction and gave her prescription. I put the lenses in a trial frame her her to test out, and she was really happy with it. I mean, really happy. Like, almost in tears. She just wanted to read. But she had some other bad problems with her eyesight (like macular degeneration, and perhaps some retinitis pigmentosa), but we didn't want to dilate her or else she'd have a seizure in our chair. She told us we can try to just use the slit lamp to get a general overview of the health of her eyes, but we knew that she would need a dilated exam under general anesthesia.

Anyway, once we turned on the slit lamp and started looking at her upper eyelid, she immediately started having a seizures. Have you ever seen anyone have a seizure? They're pretty scary. Luckily, this one only lasted about 30 seconds, but it wasn't fun to watch. She started vomiting and crying and apologizing. Mostly she was just angry. Angry at herself and her body and her seizures. All she wanted was to be able to see, but we couldn't even look in to see what was wrong. She was crying and cursing and it was just very very sad. We gave her her prescription  so that she could use her glasses to read and watch TV, but then at checkout the metal detector alarm went off and and had another seizure.

This one was bad. She was foaming at the mouth with her eyes rolled to the back of her head, her body shaking all over the place. At one point she grabbed my jacket and pulled me on top of her wheel chair. She was squeezing my hand so tight. The EMTs arrived in about 15 minutes, and her seizure was still going on. I had never heard of a seizure lasting that long. She was still convulsing when they transferred her onto the gurney, and the sped away to the ER.

I heard come the clinic chief that she is currently unconscious. I hope she will get better, but then again, maybe this is her time to go. Maybe this is selfish to say, but I'm glad she didn't pass away when she was with me. We were all seriously thinking that it could happen.

So anyway, I think I might try to visit her in the hospital tomorrow. I don't think she'll remember me, because she also suffers from short term memory loss. But maybe she will. But I should get back to studying because I have a midterm tomorrow and I haven't read through all the material yet, but I just couldn't focus and I thought that maybe by writing it all down I can get it out of my head for tonight so that I can study.

Racer Robots!

I was pretty tired of playing the same games over and over again with Olivia (Candy Land, Shoots and Ladders, Go Fish, etc.) so I decided to invent a new game. It was a pretty big hit, so I thought I would share the rules with you! It's called...

Racer Robots!

What you need:

1. Some Lego blocks or Duplo blocks
2. Cars
3. Dice
4. A track

 How you play:

1. Set up your Lego blocks at pretty close intervals all along your track.

2. Role the dice and move your car along the track, with the Lego pieces being each spot you land on.

3. Once you land at your Lego piece, you put it in your pile.  Keep going around the track until all the pieces are collected (or just until you get enough Legos...)

4. Use your collected Lego pieces to make awesome robots. Olivia's chomper robot is on the left, and my ducky robot is on the right. I think she won this round.

Swimming again

I just started swimming again during my breaks at school. I haven't been swimming since October of last year because school has been totally crazy. But this semester is pretty light at the moment, mostly because classes only started yesterday and I don't have anything to study yet. But I hope to continue with the swimming throughout this semester even as things pick up.

Some people think swimming for exercise is such a hassle, but it actually is my favorite form of exercise. Here's why:

1. You never get sweaty. You're in water all the time, so you never overheat and get red or anything.
2. You don't have to bring a whole change of clothes. All I bring is my swimsuit, a towel, and goggles. It's way less of a hassle than bringing tennis shoes, socks, shorts, a t-shirt, and whatever else. I don't even need a water bottle because I just drink the pool water when I'm thirsty. (I'm joking, I'm joking. Actually the thought of drinking pool water makes me gag a little, mostly because I saw a guy sneeze in the pool today. Blegh.)
3. You can work out your entire body and get completely exhausted in like 20 minutes. It's a pretty fast and effective workout. Plus, it's like strength training and endurance training put together.
4. You don't have to talk or acknowledge other people. I don't really like exercising with other people all that much because I kind of hate small talk and chit chat. With swimming, it's pretty much impossible to talk or listen to other people, so you can exercise with someone else without worrying about keeping up a conversation. It's an introvert's dream!
5. It gives you time to think. I can't listen to music or podcasts while I swim, and that's OK, because it forces me to think about my day and my life at the moment. It's kind of like meditation, but more tiring.
6. There's a huge clock on the wall so I don't have to worry about what time it is. I don't really like running or doing other exercises with a watch on because it always feels tight and sweaty, but then I'm always worried about being late. With swimming in the pool, I can just glance up. (I wear my contacts under my goggles so I can see the clock.)

This is why swimming is the best. Don't get me wrong: I'm pretty bad at it. I was actually the slowest person in the pool today. But it was my first time back in like 6 months, so hopefully I'll get faster. My goal is to beat the old overweight guy who swims laps everyday and then slaps his belly when he gets out of the pool.

I hate bathrooms like this

Plus, your older brother is probably right outside trying to pry open the door when everyone else is walking by,

Look what I found

WARNING: GROSS PICTURE BELOW

I was practicing some things during lunch today, and I saw this huge LASIK machine just sitting in the middle of the hallway on the second floor. There wasn't anyone nearby, and I thought it was pretty cool.

Then I walked up to it and saw this bag sitting on the blue paper

Yes, that is a sandwich baggie full of eyeballs. I guess they're sitting there for people to practice LASIK on. About 30 minutes later, a group of 3rd year students came up and were being instructed how to perform LASIK. 

The funny thing was that I was eating my sandwich out of my baggie as I was walking past this thing, but I didn't lose my appetite or anything.

Olivia's song

Every night, right before we turn out her light, Olivia gets one story and two songs. After telling her a story about Curious George and her Pink Monkey going to Kroger and bingeing on bananas, she told me she wanted to sing ME a song tonight.

This is the song:

My monkey is a princeeeeess,
Ohhhh a princessss
A piiink princess
My daddy is not a priiiiincess
My daddy is a doggie

The end

Olivia's new drawing

Today Olivia really wanted to draw a picture on the scrap piece of paper we were using to keep score on while we played Farkle. She drew the following picture can you tell what it is?

If you're having a hard time, she even wrote her own sentence explaining what is was:

It says "I iz a mos" or " I is a moose." Isn't that so cool? I'm not so sure what it says above the moose...probably a war cry or something. I love seeing her writing and sounding things out on her own along with her awesome drawings.

Triple batch of color-by-numbers!

It's your lucky day! I made 3 different color-by-numbers for you! The first two I tried to make the numbers a little bigger so that Sophie won't be so frustrated. Hopefully it works.

Here's a baptism one that I drew for Olivia to color while in church. We're also planning on doing it as part of our Primary lesson:

Here's a St. Patrick's Day/Rainbow themed one. Olivia is very excited about it:

And finally, here is a Space Ship one. The numbers are still small in this picture (sorry Sophie), so you can just color it however you want!

Have fun!

Preschool color-by-number

Here's round two of the color-by-number pictures I drew for Olivia. I'm always amazed that she had the patience to color the big areas of one color. Click on the picture below to be able to print out your own,

And here is the finished result:

Art project progress

Thought I would share what I've been working this spring break. I'm almost done! This is for the college of optometry art competition. All of the shading is individual vertical lines drawn with a fine-tipped Sharpie marker. Many, many lines...

Sea Adventures - end result!

Here's Olivia's finished copy of the coloring book. She had a lot of fun doing it, but I think she wanted more little areas to color in.

Sea Adventure color-by-number

I've been sending a lot of time with Olivia this week since I'm on spring break and Katie is super busy writing her book. Olivia and I have been drawing and coloring a lot, and we did a color-by-number page in her little Kindergarten math book. She really really liked it, so I thought it would be fun to make another one for her. So this afternoon, while she was taking a nap, I drew out this little picture here. I think it turned out pretty nice. I thought I would share it with you! Click on the picture to see the pdf.

Once you print it out, just color this boxes in the left hand corner with the colors you want to use; that'll make it easier to use if your kid can't read yet.

Have fun!

Where I am meant to live

I just found the spot where I am supposed to live:

This is the corner of Bryan Street and Lewis Street.

This is found in the city of Bryan, Ohio. It's kind of in the middle of nowhere. See?

I found out some interesting things about this great city. First, there are only about 8,000 people that live here. Second, it is known for manufacturing three famous items: Dum-Dum suckers, candy canes, and Etch-A-Sketches. Katie said that of all the candy that could represent me, perhaps Dum-Dums represent me the best. I resent this statement, because Dum-Dums are pretty trashy candy. If only Bryan, OH would manufacture Jolly Rancher Jellybeans...those things are the absolute best tasting candy in the world.

Bryan, Ohio looks like a pretty nice place. 

Olivia can be pretty mature

I just put Olivia to bed and as I was leaving she asked for a drink of water. She took a long sip, then laid back down. I noticed she had her cheeks puffed out, and I thought she was just being silly, but it turns out they were full of water. I know that now because I squeezed them. The water squirted out all over her face and on her pillow.
I said, "Oh no, I'm sorry Olivia! I didn't think you had water in you cheeks!"

Her reply was so great:

"That's OK daddy, it'll dry off in a little bit. But next time will you please not do squeezies on my cheeks?"

Crazy stories from work

So it's been a while since I have posted on here, and I thought a good post to warm up to writing again would be to share some good stories from work.

Nothing too exciting ever really happens at school because we can't see anything too complicated, but that is definitely not the case at work. For instance, last week a guy with Downs Syndrome came in and needed some surgery because half of his face was paralyzed. He couldn't blink one of his eyes, so that made that eye all nasty and it had a huge ulcer. They ended up having to permanently sew his eyelid shut so the eye wouldn't get worse. Me and 4 other people, including his mother, had to hold the poor guy down while the doctor sewed his eye shut. He was screaming and crying and straining the entire time. It just reconfirmed in my mind that I am very happy with my career choice and I don't want to be more invasive than I have to be.

Im too lazy to think of another story, so you just get one. Also, I am trying to learn some guitar chords. I know D, G, A, A minor, and C. It's actually surprising what songs you can play with just those chords.
