I'm loyal (but not stupid), and I think holding grudges and hating people is a waste of energy.

I had a roommate my junior year of college who turned out to be quite an unstable person. She transferred in during my sophomore year and lived across the hall from me (this is how we met). I was feeling a little exasperated with her one day when I overheard her alone in the hall, talking to her brother on her cell phone and saying, "Yeah, I've got a roommate for next year. It's this girl who lives across the hall and she's really cool. She has long hair and wears her dad's clothes and when I first came here I thought she was just one of those weird hippie kids but she's turned out to be a really good friend. She's very sensible, she never tells secrets, and she doesn't bail out on me when I get emotional about things. I need that kind of support right now." I am, above almost all else, not a people-person; it never occurred to me that somebody else might need me for any reason.
