man.. i'd ask her to replace all items that were covered in vomit - ie all the seats and carpeting.
I can't stand people who just drink like there's no tomorrow and become a massive burden on other ppls shoulders. Alright, fine, you've organised a lift home, but ffs drink to how much you, yourself can handle, not til you're so farked you're choking on your own vomit and can't even walk without someone else guiding you. Everyone should have learnt their limits when they're teenagers..
morons.

ps, I can't believe you still took her home!
