Dancing at my prom?

If you look at the other people dance, you won't feel so bad. Most people are horrible at it. If you want to practice though, start out by closing to door to your bedroom, put on your favorite song, close your eyes and let yourself move with the music. This is how I taught my thirteen year old. The most important thing is to go with the beat. It's easier at first if you close your eyes so you don't have visual distration. Don't worry, you'll be fine.
