If a boy starts to like girls too soon, other boys will call him a faggot. Leaky balls don't bounce high or hard, but they're much more fun to play with.

Last year's cool toy is this year's dull zone. If you're the last one left when the teams are chosen in the first week of first grade, you'll be the last one left when the teams are chosen in the last week of high school. People will kill you if your existence disturbs them, even if you've left them alone. As soon as you're old enough to do what the older kids are doing, they stop doing it and start saying it was stupid. The people who say they're the coolest are just trying hard to find something to imitate.
