Go...come on...its your senior prom. Its a once in a lifetime thing, unless you go to another at a different school in addition to your own

. Its quite rare to get an opportunity to do so much with so many women. They're all there to have fun and laugh and dance, they don't care who does it with them....and wouldn't it be great for you to be the one doing it with them or helping them have a blast. Hell, if you're a really good dancer, you could show them some moves haha

.
Bring a date, you don't have to spend the entire prom with them. Go around asking other girls to dance, or just go onto the dancefloor and start dancing with random girls. Do it with some of your boys, you can all have a bunch of laughs dancing with random women, or even dancing like an idiot to attract attention and get weird looks.
Mingle like crazy....I Know For Sh1t Sure I Am.
To sum it up, yes prom is a big deal to me.
Trust me...You'll be glad you went

.....and there's always post prom stuff to do.
You reep what you sew...
