Let's see...when I was 15 I thought:

1) Smoking was cool and smoked myself.
2) The drinking age in Canada should be lowered to 15
3) The drivers age should be lowered to 15
4) Captial punishment was right
5) Canada was the best country in the world
6) The US was kind of cool and I wish we had a president
7) Hockey sucks
8) Nirvana and Green Day rule

I could go on. :)
