Pet peeves. Got a couple years to read all of mine? heheh - here's a couple off the top of my head.
Driving: Someone pulls out in front of you when they could have waited, since there is no other car behind you for 18 miles.
Work: Weather harbingers of doom. When snow is on the way, a few office folk spend all day talking about how the amount of snow will be enough not only to bury the entire province, but surely kill at least half of the population as well. Relax, we'll get 5cm.
Eating: People that chew with their mouth open OR make a lot of noise with their chewing. Nuff said
ATOT: Thread crappers - the REALLY senseless ones, like "Rap sucks".
