Only three?!?! There are so many.
1. Drinking, soooo much fun the night before, not so much the next morning.
2. Cheating on a girlfriend, I have not done this when I was dating my wife. I was seeing a girl I really didn't care for, hence why the cheating took place. There was a <strike>little bit</strike> a lot of guilty pleasure #1 involved as well.
3. Speeding, I love driving fast. The faster the better.
Three favourite Canadians.
