If you ever find yourself in a situation where you are dealing with a high or drunk person, keep one thing in mind: Agree to whatever he says, and try to walk away from the situation!
The last thing you want is getting into some kind of trouble by upsetting the irrational man, who can possibily be a danger to you, others, and himself. On the other note, try to refrain from being that person people may want to avoid as well. I don't believe there's any excuse to hurt your body in such way to experience temporary pleasure (if that's what you want to call it).
Question: Have you ever been in a dangerous/uncomfortable situation involving an intoxicated person?
