i didn't go to prom but i did go to an afterparty, it was pretty wild, a few of the people got so wasted they vomited and passed out and in general made things kinda stuffty for the rest of us. parties aren't usually my thing
you made the right choice though, don't get involved with that stuff. Parties are fine, smoking a bit of weed is fine as long as you don't get caught, getting drunk as forget and vomiting and doing crazy stuff isn't as fine
