WHAT JERK AT A DANCE WOULD TURN SOMEONE DOWN?!?!
Sorry, but I just don't think that that's unacceptable. It's a Church dance. Why would you turn someone down? If they ask you to dance, you say yes. It's not like you're dating now. You just have to make small talk for three minutes.
There is a kid that I asked to dance that I know from a show and he said "thank you so much. I was worried no one would dance with me. I asked a girl over there, but... but she said no."
I felt so bad for him!
