1) When people come up behind me and read over my shoulder.

2) 12 minute voicemail messages. The purpose of vmail is to let me know you called, not carry out your entire side of the convo.

3) People who cc: everyone on emails. This happened all the time at my old job. We called it email poker, because everyone was always "raising" the ante by adding a higher up on each reply.

4) Politicians in general

5) People who drive slow in the left lane and only move over after you pass them.

6) People who litter

7) People who try to pass themselves off as being smarter than they are by using big words that they use in the wrong context half the time, or discussing things that you covered your 2nd year of college yet they're just learning them now. Like they're some sort of genius for learning the periodic table.

8) People who are generally aloof to others

I think that's it
