I think that being cool is just about being you, and not trying to be someone you're not or hanging with ppl just because they appear "cool"!As its explained, drinking and smoking are sooo "cool"... but what do u really get out of it?... A lifetime of regret? Now I am not saying that drinking is always bad, if you are of legal age and u don't drive home it's not as bad... but having to sneak it and risk your life or others just to look cool actually makes you LAME! Sometimes, when ppl try to act a different way... thinking they're cool, they actually end up looking worse! The best way is to stay who u are!... and don't change unless the changes are good, cuz it's better to be u, than to change for ppl who would leave you in a heartbeat!
