Bad spelling does get under my skin just a bit. But the text speak makes me want to slap people. I swear. Have a little respect for the english language.
I also can not stand when I see people alternate upper and lower case letters thinking it makes them look artistic or something. iT iS sTuPiD! Seriously....that takes a whole lot of time that could be spent doing something that doesnt make me want to break your fingers.
Oh, and bad drivers. If you can not respect the rules of the road, use common sense, and stay the hell out of my way and off my ass then you should learn how to take the bus.
