my kids are too young to make a parental call - so i will give you a kid's perspective.
when i was 16 (LONG ago), i would have taken dope if given to me. i would talk to boys if they talked to me. i would have a drink if someone offered it to me. i wasnt stupid, i was naive(ish).
even good kids can turn their judgement off on vacation.
also, i know a former boarder who only asked his 16 yr old son to move the cart from one end of the lot to another - well, the boy hit a firehydrant, caused $ damage to both said cart & property, and the south end was out of water for a few hours.
