Further pet peeves:
Busywork. (No, I DON'T want to waste my time on pointless work! I can't think of anyone who DOES!)
Condescension. I HATE it when people are condescending towards me!
When people act like they're so much better than you just b/c you like cartoons and Muppets & they don't.
The "street clothes" versions of the Muppet plush dolls. (Is that "ZEN" ANIMAL??? What the heck???)
When I like something BEFORE it becomes popular, and then it becomes popular, and the people who previously mocked my obsession now suddenly like it, too!
