My #1 pet peeve are bad drivers. I'm putting together a website describing some of the stupidity I've seen out there. People who tailgate, cut people off, flip off other drivers, drive too slow in the left lane, weave dangerously... DRIVE DRUNK...
I can't stand it when parents don't control their children. On one occasion I was staying in a hotel for the weekend, and it turns out there was some youth soccer tournament that weekend and they'd booked out most of the hotel. The kids were running up and down the halls screaming, and the only security guy on duty couldn't be everywhere at once. Where were their parents? At the bar getting smashed.

In five years, when little Susie is 14 and pregnant and Johnny is 16 and in jail for doing drugs, they'll be wondering where it all went wrong, because "it couldn't possibly be bad parenting!"
