I kinda agree, and kinda disagree. I didn't have pop when I was really young, and I used to drink it alot. When I started being allowed to ask for it, I drank it because it was there. And then I wanted more. I think I was addicted to pop, and I almost stopped drinking it completely about three months back (Except for rootbeer when eating out. I love rootbeer and won't give it up) Until I went away to work for a month and it was pop or coffee to drink. Then I was drinking 12 cans in 2 or three days, plus once or 2 at work per day. It's because I wasn't allowed to have it often, I wanted it to begin with. On the other hand, I never really had the whole "drugs are bad. Drinking is bad. Partying is bad" and yet I've never partied, or done drugs, and only occasionally drink. Probably because I never wanted to.
I thinks it the whole you want it because you can't have it thing, for the most part. Like a little kid not playing with a toy, until you take it away from him, then he cries and wants it back...
