I know a lot of my friends who do this kind of, er, stuff...
In a sense, it's a shame my generation brings onto itself. Suffice it to say, I live in a generation where "It's all about me, me, and me." These kids have no common sense--something that's equally apparent on campus and in public.
It's a sad commentary on what our society has devolved into. OTOH, all hope isn't lost. There are people with common sense and who know right from wrong. And there is faith in God above...
And these people are going to be running the country fifteen to thirty years down the road? Utterly appalling.
It's no shame to want to go out and have a good time with friends. Alcohol, for better or worse, is part of that for most adults.
NYC is much safer now than it was when I was a teenager. 18 & 19 year old girls who don't know their limits (and at that age, who does) should go to these clubs with male friends they trust. If they don't have male friends they can trust, then perhaps some introspection on their part would be better than clubbing.
