Oh! Here in our country we have a tradition called Debut, its when a girl turns 18, she also throws a big party. haha.
Awww, you can do it. Last February (on our prom) I was asked by my classmate to dance, I don't like him actually but he's so damn fine.
Of course I dance with him because i would feel bad if I turn him down.
I guess you have to dance with her so that you won't hurt her feelings.
