Spelling and grammar errors stand out to me like bright, flashing red lights. I particularly can't stand "your" being used instead of "you're". That almost makes me wince when I see it. And the ever-increasingly rampant misuse of the apostrophe is terrifying. Basically, the effect of the Internet on the English language is driving me nuts. I hate letters being used instead of words. I hate improper or completely missing punctuation.
I've developed a lot of driving pet peeves lately. I just can't believe the way people act out on the road. I too get really annoyed when people don't use their signals. And when people hang out in the left lane, holding up traffic and completely ignoring the "Slower Traffic Keep Right" signs, I want to drag them out of their cars and beat the living shit out of them. Every time I see someone putting along in the left lane with car after car coming up behind them and then pulling over to pass them on the right, and they simply refuse to pull over into the right lane where they belong, it drives me up the wall. Then there are the people who come up behind you when you're caught behind someone like that and ride your ass. Apparently they think that by getting as close as possible and swerving from side to side, they'll somehow get you to go faster than the car in front of you.
I've seen people play games with me on the road. I've had people "attach" themselves to me going down the interstate in the middle of the night, pulling ahead and then dropping back behind over and over again. I really don't understand the sudden speed changes people make sometimes for no apparent reason. Pick a speed and stick with it. I really love when I pull out and try to pass someone and they fucking speed up, trying to match you. It's like they think I'm insulting them by trying to pass.
All these driving issues come down to having respect for the other drivers on the road, and so many people just don't seem to have it. In fact, a lack of respect for others in general is a pet peeve of mine. Rudeness, arrogance, inflated self-importance, all of these things bug the hell out of me.
Whoever mentioned being annoyed by people who don't make room to pass them on escalators, I completely agree. That's always been a pet peeve of mine. I walk on every escalator, up or down, and I always seem to be the only one who does.
Whoever mentioned people who make it their mission to convert others to their religion is also quite right. That really pisses me off. I see religion as a personal thing. Believe whatever you want, I don't care. Whatever works for you is fine. Just don't try to push it on me.
Concerning baseball caps only looking okay at the ballfield; let's not forget the golf course. Backwards always looks stupid, however, and any variation of sideways looks completely asinine. I also think that a ballcap on a girl with a ponytail through the back looks good, though.
I can't stand people who buy concert tickets specifically to sell for profit. Those people can go to fucking hell.
