1: When people forget to capitalize, punctuate or spell correctly in stories(not RP's).
Ex:
"kate walked don the stret and didnt realise that her shue was untyed"
Not that I hate people who do this in stories, but it just annoys me somehow.

2: When people knock into my arm while I'm writing a sentence and messes up my writing.
Seriously, I write in extremely dark pencil, so when I have five minutes left and I spend 3 minutes erasing pencil marks, guess whose getting a face full of Yandere?

3: When people interrupt me in the middle of a discussion.
Me: Oh yeah, I just wanted to ask you guys-
Joe Shmoe: DID YOU GUYS HEAR ABOUT THE NEW MOVIE? OMG IT'S COMING OUT SO SOON I CAN'T WAIT!
Me: -_-
Joe Shmoe: What?
Me: -digs hole and buries- Anyway..

What are your pet peeves?
