Prom was a big deal but I did not want to go.
My school was full of assholes and I didnt like spending the school day with them. Certainly did NOT wanna spend my free time with them, especially when I know damn well they'd be acting even more disgusting than usual.
Having said that, if I had a girlfriend at the time or even been able to get a date just for that, I would have gone.
I'd have been miserable but it makes the girl feel special to be there in her nice dress with the corsage. And girls who swear to keep their virginity until marriage often slip on prom night. LOTS of cherries get busted.

(Up until that point most gals just give HJ and BJ. Something about prom night makes them change their minds.)
If the stories I heard the following monday were to be believed, I was right. The guys turned into even bigger assholes and women turned into even bigger bitches.
My understanding is that because of the assholes, the bitches (and bitch-fights) and drunks, the evening turned out to be less than pleasant.
Good.
A harsh reminder to those spoiled fools that life doesnt owe you anything, especially happiness. You have to make it happen for yourself.
