-When people chew with their mouth open
-When people drive way under the speed limit. A couple MPH under is fine, but 10 under? 15 under? Really?!
-When people try to talk to me when I'm reading. This happened all the time when I was in high school. I mean I like talking to people, and if it's just a short sentence or two that's fine, but when I'm clearly involved with my book and you want to have an entire conversation on something that really isn't that important at the moment. Maybe I just get too into my books.

-People who constantly talk during movies, especially at the theaters.
-Overly competitive people. I'm somewhat competitive, but some people seriously need to chill.
