He's an idiot

I'm gonna complain here. I got a guy at work who I've mostly always respected and liked. Last month I didn't say hello to him and he got mad at me, which really upset me. The other day I said hello to him, and he got mad at me. We were sitting at a lunch table and he called me an "asshole". In front of everyone. I was really pissed off, I jumped up, told him what I thought of him and stormed from the room.

This guy has done this to other people in the past. And you know what? I am not going to take this. I am not his pansy, and I will not sit down and let him walk all over me. He's insecure so he needs to be a bully with people. For some reason I am his latest scapegoat, and that sucks. I am fighting back. I already checked with HR about submitting a formal complaint, and I can. Ha. I bet he'd love that. Tomorrow I hope to sit down with a mediator and tell him what I think.
