They are dancing. They were discussing how to not make errors. They are listening to a song and learning how to go along with it. The woman is a very good dancer and the man is trying to be a good dancer too. They both know about the dance and are trying to get better. If they know what is going on they can correct their errors. They are friends that met at a party and had a good time! After this they become even better friends and they become better dancers. They are young and are at the prom! This reminds me of my 3 siblings; they weren't strong dancers when they were young.
