Here's some of mine
Hair in the shower drain...just ick!<---This also falls under my weird phobias list
Crumbs in my bed
People who talk on the phone or text while driving or crossing the street on foot. Then when they get hit because they weren't paying attention they want to sue somebody.
Zealots who act like they know God personally, and what he wants...and use that to make other people miserable through bullying, and violence.
Automated phone-bots-Is it too much to ask to just talk to a REAL human being?!!!
People who abuse animals or children or old people or disabled people.
What's some of yours?
