I was left alone and never had any issues. Usually it was just a bunch of girls getting together for a slumber. The idea of a wild animal house blow out was always out because everyone knew we'd get caught.
Even my party story is actually very tame. A party was thrown and it got out of hand- but not in a drinking, dangerous way. It was just kids having too much fun. And, if I recall correctly, almost every teen incident of too much fun results in somebody's lawn getting toiletpapered. In my case, there were two parties on the street- both of them harmless. Except we each decided to *prank* the other party. Even now my parents agree they completely overreacted by grounding me for so long. And I managed to go to college, get a job, move out and not mooch off them in my adulthood and am a contributing member of society.

I think the teen party is a right of passage. It is what it is.

This story is a kid with MUCH bigger issues than being left alone overnight. The problem here is not a lack of supervision. It is a whole other set of mental issues. Ask any teenager you know and they can tell you that catching your house on fire is wrong.

I don't have children. But when I do, I'll hopefully raise them with enough common sense to spend a night alone in their own home without burning the house down! lol
