When people interrupt me while I'm reading or watching a TV show and I hint that I want to be left alone and they don't get it and then I tell them and I'll be right there on a minute but they get mad and I'm already mad or missed something important. =P

I have to admit that people who chew loudly are one of my pet peeves,also people who shuffle their feet when they walk, I think that's why I was happy that 'Mika' got his come uppence in Paranormal Activity,kept shouting at him to 'pick your feet up,man.'

yard sales that have books thrown in old boxes!

People who chew loudly/with their mouth open. It drives me up the wall.
Also, the pronounciations 'nook-yoo-ler,' 'Eye-rack,' and 'Eye-ran' for 'nuclear,' 'Iraq,' and 'Iran'

Mine are people who slurp their coffee (or tea), and people who shuffle their feet while walking. Only 2 in a long list that I won't enumerate!

people who chew ice. i cannot stand that sound

The phrase "pet peeve". Also, people who are so stubbornly insistent in their principles so as to not understand others.

people with their tongues out when they are concentrating really hard

I hate it when people leave my door open.
