1. Bad Oral Hyegine. The worst is having to share a workspace, or an elevator with someone who has bad breath and breathes with his mouth open. gross.
2. Lots of body hair. So gross.
3. Smelly people. I can not handle disgusting smells. I dry-heave.
4. Obnoxious people. They drive me nuts. I mean I like to hear the sound of my own voice, but come on. Some people need to be gagged.
