I got the difference program working this morning so I think it catches all differences between two first class databases. In the afternoon we left for our private lesson with Robert. This was good. We fine tuned our Cuban walk then added some open breaks to the mix. After a quick bowl of Brunswick Stew we left for Argentine Tango. Andy was back so the class was not as much fun as with Robert. Nancy, Steve and Mary made up the rest of the dance partners. After Tango we stayed for Robert's first waltz class of a series. We learned to waltz backwards while switching our lady from right to left. We came back tired but happy.
