What are some things that people do that drive you absolutely batty?

Well for me its not so much what people do as much as it is for what they say like for an example my girlfriend will be sitting less then 2 feet away and Ill ask her a question and evreytime she says "WHAT" but heres the thing, she heard what I said because I always say "FORGET IT" and she will go on and answer my question I asked previously. This is one thing that drives me crazy. Another thing that really bothers me is teenagers who walk around in public places swearing up a storm and spitting everywhere. For one I dont want my kids picking up that language and for 2 how gross is it when you step in someone else's spitt? GROSS! The other day on the way hope I was waiting for a bus and I guess some kid spit on the ground, well I didnt see it and the girlfriend did but it was to late I stepped in it but you would think no big deal right? Well when I looked down it was a little puddle of blood he spit out I stepped in like disgusting. I have many more but these are my biggest 3 things.

I can't stand it when people talk really loudly on their cell phone in public so that everyone around can hear their entire converstation. I also hate it when cars pull across the whole crosswalk at an intersection, forcing people who are crossing to walk out into the intersection to cross.

One time when i was on a bus going to work. There was a girl who was twirling her hair. It was ok at first but she kept doing it and doing all the way to work. I wanted to reach over and slap her hand and say STOP! I was glad to get off of that bus.

Some things that people do that drive me absolutely bonkers - 1.) People who cannot type an entire sentence without saying 'u' or 'plz' or things of that nature. That drives me insane. 2.) Someone who cannot shut up for two minutes, to let me get a word in edgewise. 3.) Emo people. Plain and simple. I'm not talking about truly depressed people. I'm talking about people who have nothing to be depressed or to complain about, but yet, they find flaw and fault in everything, and somehow, they become the victim. That pisses me off.
