5 things other people do that annoy the piss out of me:
1) Butting into a private conversation.
2) Sitting behind me reading what I type over my shoulder as if it had ANYTHING to do with them.
3) Checking on me and my work, as if they were my supervisor.
4) Kiss so much ass that only the Ass respects you.
5) Eavesdropping on private conversations at work while pretending to looking busy, like being on the phone.
Oh, what a coincidence. The guy sitting behind me does all of that. No wonder the nicknames he's picked up are cruel...
