John's TOP 10 Pet Peeves:
10) People who do not buckle their kids in the car (you see their kids moving all around as you're driving behind them)
9) People who send you chain letters via email
People who do not say, "Thank you."
7) People who speed up (in a car) to get in front of you then drive at a snail's pace
6) People who don't turn off their cell phone at the movies (or at least turn on vibrate)
5) People who play games, IE: ask your opinion on something then analyze it.
