I agree, experimenting is what makes life fun and worth living. I don't care if people are clean, good for them, but it's when they go around advertising it is when it gets annoying as hell. Or like when you're talking to you're friend about buying a dime and some random emo kid comes up to you and says "you shouldn't do drugs. They're bad for you."

"You shouldn't eavesdrop, it might get you punched in the mouth"
