When did an end of the year dance turn into a 48 hour party extravanganza?
The whole prom thing has gotten completely out of control, IMO. Not just the all night parties, hotel rooms and sleepovers, but the limos, spa days, thousand dollar gowns and expensive restaurants.
I gotta say - at my prom, we went to the dance, had a great time, and came home. It seemed much more "magical" to kiss my date goodnight at the door, when we were still dressed up and starry-eyed than my friends, who said goodbye to their dates the next morning, bleary-eyed, hungover, and in their rumpled, slept-in tuxedos.
If you aren't comfortable with the coed sleepover, by all means say no. I certainly would. Teenagers aren't going to be ruined for life if they can't have a sleepover on prom night. It might seem like the end of the world at the time, but they have their whole lives to have all-night fun with their friends.
When they are adults.
