Pet peeves of the day:

People who give out your e-mail address just so they can maybe get free tickets to something. It's all a load of bullshit and now I'm gonna get lots of spam mail.

People who pretend they know how to pronounce things in foreign languages when they so obviously don't.

Broken cars.

People who overanalyze Steinbeck. Steinbeck is so upfront about everything there's barely a need to analyze his writing, let alone overanalyze it so much that you start seeing things that aren't there. (English nerd)

People who owe you money who know they owe you money and could easily give you the money but still refuse to.

Substitute teachers who actually try and teach you things when the teacher's not there. Honestly, who's that dumb?
