Drinking is not the most important things in the world.

In the US for sure, teenagers start to idolize alcohol and eventually it becomes the pinnacle of cool for some. "Parties" end up revolving around just the alcohol and getting completely wasted. Trust me, you are not a cool, as charming, etc, as you think you are when drunk. And there's are, absolutely people who will show up to these parties expecting to exploit drunk people.

I'm not telling you 'NEVER DRINK!'... More like, you don't need to try drinking a lifetimes worth of alcohol everytime there's alcohol around you. 1 drink can be enough. And don't hang out with people who push you to drink or don't accept 'no' as an answer and try to peer pressure you into drinking.
