The brain fully matures about age 25.  Considering college kids 18-22 years old with raging hormones injesting ETOH, MJ and who knows what else is the perfect recipe for creating out of control behavior. That we know but suggesting or hoping they will emotionally evolve to a level of responsibility to understand how intrusive and selfish their behavior is...is just short of a pipedream. They won't because they can't. They can not self discipline ergo they by in large don't have enough developed cells nor skills to operate independently and responsibly. They still require supervision at an appropriate level like when they were 12, 16, 18 or even 22. That's the role the Party Patrol plays but translates to pretty much chasing one's tail. If one really wanted to make a dent in outrageous parties the supervisory element must be more present. How about landlords be fined if a property has at least 2 notices about "out of control" behavior. Would bet thr landlords would evict or ??
