My roommate, Moriah, is incredibly bright, cheerful, and open-minded (her best friend is a gay guy who comes over frequently.) Her boyfriend is over right now, and he's got to be the most pessimistic person I've seen. All he's been talking about is how much life sucks. I am so amused.
Btw, my suitemates are cool too. I wouldn't be best friends with them, but they're nice and we all get along well. So far, I don't think I'll be moving out this time. :)
