Don't fucking smoke during prom. It will just make you lethargic and a slower dancer. Drinking on the other hand would be a good choice as long as you aren't driving afterwards. Just ask her beforehand if she'd like to go clubbing, and if that doesn't work out, just find a hotel party. There's ALWAYS a hotel party during prom. All I know is that my prom back in high school was possibly the worst in history. To make a long story short, prom ends, my date's stalker ex comes up to my car trying to fight, he talks to her and makes her cry, we head to a hotel party only to find out that he is there waiting for us. She cries some more, I take her to a ranch where I have my horse for some odd reason. She seemed to like it so I kissed her and took her home. Overall, a shitty night.
