I think everyone has at least one pet peeve. I have 2 big ones....immaturity. Act at least your age please. It drives me nuts to try and have a conversation with someone who is my age only to have them act like they are 12. And the other is people who are close minded. The whole concept doesn't make since to me. Why can't people accept others for who they are. I just can't understand it and it ticks me off more then just about anything.
