The only language thing that bugs me irrationally is when people write u, ur, etc instead of you, your, and so on. Im not trying to be judgemental or anything, but the moment someone does that they instantly become less of a person to me. I feel like I'm talking to a wall or a robot or something, but then that's probably because of the amount of times I'll be playing an online game or something, and someone is typing like that and they just seem stupid. Not everyone of course, but its happened so many times that I see people doing that, along with spamming multiple ??????????? instead of just one, and they can't seem to grasp a single thing I say to them.

I let it slide in text messages, since it can be a little more awkward to type the whole word out, but people doing it on a computer (or the way my sister used to do it in handwritten letters) would make me so angry. It just seemed so lazy.
