to be completely fair this question is kind of circumstantial, i mean do you have a girl friend, is it jr or senior prom, is it something that you'll never be able to make up for. Now if i had a girlfriend and she was desperately set on going to the dance, i'd go with her, you can sesh any other day, but you know her heart will be broken in half if you ditch something that isn't important to you, but to her is important, and she will never live it down. now if you're single on the other hand, shred the gnar gnar
