I once lost a diamond at a debutante ball!
Really? where you a debutant youself? or a partner for one of them? anyway do you know ballroom dance?
I got dragged to it, but I know a little bit of how to ballroom dance. Do you know anything about the balls?
I know that Ballroom dance is set of partner dances that are practiced socially and competitive around the world.  But I don't know how to do it.
