I really can't stand this guy

This guy at work.... I really hate him. I don't want him to talk to me. I don't like him. I think he does a really bad job at work. I also think he's kinda dumb. He can't figure out how to look stuff up. He's completely uninterested in learning anything new. He covers up anything he doesn't know with a bunch of jargon. He talks a lot, but never says anything. It makes me so angry. Oh and while you're at it, my cube is not your office, you don't own it, please do not treat it like your property. Let me know when you are approaching, do not approach until I acknowledge your presense. AND DO NOT TALK TO ME OR ASK ME QUESTIONS WHILE I AM ON THE PHONE. AND FOR GOD'S SAKE DO NOT MAKE FUN/INSULT OTHER EMPOLYEES IN FRONT OF ME. It's disgusting and unprofessional. Almost as unprofessional as your emails to customers are.

Me being so angry with him, was reading an email, I hear him approach, do not turn to talk to him immediately b/c I was in the middle of a sentance and he did not even announce his presence in any way. So what does he do? He starts reading the email over my SHOULDER!!!! WTF? Then he makes a semi-snide comment about another employee who he clearly has taken a dislike to (for no reason). Then when I'm quiet and do not say much to him, he's like "are you sick? you don't seem like yourself." I just want to scream "I"M SICK OF YOU!!! That's why I'm not talking to you. I think you're disgusting and a horrible person to boot. Please don't talk to me anymore." But you can't say that. And I just bitch in my blog about it.
