"...exchanging phone numbers with strange men...."
Yes, this part is very bad. And this girl broke the #1 rule for partying girls: don't leave your girlfriend(s). They probably were all so blitzed the boys didn't realize she had fallen. Her friends should have insisted she re-join them when she called at 1:30.
I feel very bad for all these people, but I gotta tell you, you watch other people's children even more closely than your own.

Unfortunately, today there are too many parents who don't watch their OWN kids, so certainly can't be bothered to keep track of yours. :\
