I think it's important for kids to experience wild raging parties maybe just to see the stupidity of drunk adolescents. A lot of mistakes I've made will not be repeated and those learning moments are invaluable. The lessons might never have been learned without some stupidity in the first place. Yes the risk that can come from alcohol and young adults is high but a seminar at school won't change you like a first hand experience. This has all been pretty vague but maybe you get the point.

Good judgement comes from experience and experience comes from bad judgement.
