kittooi: That's a hard one.... There's no one that I personally know that I truly dislike, I just dislike parts of their personality or lifestyle. Though, I do have a strong dislike for this orange colored guy who doesn't know how to use twitter very well. Also anyone who doesn't stop and listen, but instead just assumes things.
I dunno if I'm lucky, the people I dislike most aren't in my life in any way, so I just don't bother to particularly remember them. However, my memory is also terrible
