This ain’t Boy Meets World brehkid: can I spend the night at so and so's place?
mom: yeah (doesn't call the parents up to make sure it's ok) (doesn't tell her to call her when she gets there) (says she doesn't trust her daughter and has reason not too, but won't follow up on where her daughter says she'll be)
dad: where are you going?
kid: just some party
dad:just be careful (doesn't ask for address) (do you know who's throwing it?) (be back by a certain time?) etc etc...
