Am I that hard to live with?

Now really, am I? I bet even some of my worst roommates would say that I have had some agreeable parts about my demeanor. I am not mean in the slightest!!! Well, everyone is kinna mean, but I don't intentionally hurt someone's feelings unless they pissed me off and they truly deserved it. So yah, I think even my worst roommates would say I was a nice roommate or something. Minnhat for example, my Vietnamese roommate, she had no clue that I didn't like her and was totally dumbfounded (ok she's was always dumb) when I moved out and didn't tell her. Annette probably had no idea that I didn't like her either. Is it me? Am I the one who finds the problems? I know I don't speak up about my problems with other people, but I swore I was agreeable. Why do I always get stuck with people I can't live with???
