I can't stand it when people talk on a forum or via text message with incorrect punctuation.
I can't stand people who write your instead of you're, there instead of their, and so on.
I have this thing about getting in Andy (TE7two)'s car and having to mess with the windows and every button in the car.
Every person in my cell phone contact list has to have a full first and last name.
When I organize they either have to be by size or in alphabetical order. It usually is the latter.
I also can't stand "one uppers." We have about 4 of them that work in the shop with me, so it's a constant battle to tell a story.
I don't ever take my contacts out. The only time they come out is if they fall out or I think it's time to put a new set in. I know it's not safe, but it's just what I do. I just can't stand putting them in and taking them out.
