"No food or drink in the lobby."
Does that mean we're allowed to or not?
Something else that has bothered me was whether you should include a comma after an "and" in a list. For instance, I always wondered if you would say "I brought a pencil, a notebook, and a calculator" or "I brought a pencil, a notebook and a calculator." I'm pretty sure you should have a comma before the "and," but the opposite it true in German. You never have a comma and an "und" next to each other. That has always thrown me off.
A funny example of this is a quote from an acceptance speech: "I would like to thank my parents, Ayn Rand and God."
Another weird thing: I say, "sure" a lot now. I don't know who I picked that up from or why, but I say it in response to the most random sentences.
