Hmm... probably this one co-worker of mine. She's a complete hypocrite, a racist (always has a nasty thing to say about anyone who's not black), and is very judgemental. She thinks she knows EVERYTHING (even when she's completely clueless), but refuses to believe that she's ever wrong. Woman drives me up a wall LOL
I think if I got stuck in a lift with her, I'd probably kill her and claim it was in self-defense.
