Ever go to a party, and you only know one other person, and you realize that they haven't shown up yet? Now imagine how awful that would feel if there was no booze at the party.
Owning your own hookah is a pretty big commitment to a certain type of lifestyle. When you make that commitment this young, it's a sign of devotion to partying for the rest of your life.
Look, I don't want to dissuade anyone from doing the responsible thing and crashing on the floor instead of driving home after a long night of partying.
Just be aware of what underwear you are wearing that day...
