caf prom was awesome. cheap tickets and the same shit friends from other schools mentioned.
judging from your post, you seem well liked in your graduating class. probably more popular than you think! when you see everyone that you've spent years with in suits and nice dresses, you'll feel ecstatic about being all grown up.
and don't worry about a date.. best be going single and doing whatever the fuck you want without being chained to one table/group.
hope you have fun and tell us of your adventures if you don't go!
