That one person you can't stand

Why does it always seem that no matter where you work, there is that one person you can't stand, and your always stuck with them? A friend of mine can't stand his boss (of course this guy is a real dick), another friend works with this girl that is a real piece of work. I'd like to say that I love everybody I work with, but I'd be a liar. There are a few people I can't stand, but I do my best to put up with them. In a short list of things that drive a person crazy:
1. If a person treats you very rudely the FIRST time you ever work with them, you can be sure that you're not going to get along with them.
2. If they deliberately mess with your station, especially if it involves money, you can bet you're not going to get along.
3. If they suddenly stop a conversation with another employee the minute you walk around the corner, you can be very sure you are going to hate each other.
4. If every day you don't work with this person is full of sunshine and rainbows, you can be damn sure you absolutely will hate their guts.
5. If your the subject of an unwarranted tirade, general for something you haven't done or because you didn't do something for them that instant, you might want to look for another job, because this job is toxic!

In general, if you have that one person that annoys the hell out of you, do one of two things: get another job, or go postal on their behinds. (I highly recommend the first one!)
