For the most part, the parents that would think this was a great idea were so trashy that I'd never let my kids near them, nor would my kids have wanted to hang there.
It seemed to be more about the parents wanting to be young still by reinforcing how young and with it they were and less about the kids education and safety.
Also, I knew of one of those moms that was always trying to seduce the teen boys. God, she made an idiot of herself at 50 years old and 250 lbs.
As for my kids, we drank a glass of wine once or twice on special occassions and I talked to them constantly about the dangers of drugs and alcohol and they have had problems with neither so far. Hopefully it stays that way.
Sorry, such scenes were completely avoided because they were promising nothing but trouble really with those immature "parents" in charge.
