I don't have roomates like that, but I have a brother. He messes up my stuff, could care less about it. One time he backed into my Z and didn't think anything of it. Anyhow I know how it feels when your around people that don't have the same interests as you. It gets really annoying, you don't want to do the things they like to do and they don't want to do the things you like to do. My oppinions about people like you described are that they have no hobbies and no life. And I agree very much with Drew, I just don't let what people say bother me and very few things stress me out.
