Social Dancing nights are a great place to put into practice what you've learnt; not only the dance steps, but also the socialisation, telling your partners they're great and having a drink and a chat too.
Organise to meet a couple of people from your class at a social night and enjoy the spectacle, the music, your own dancing and the excitement of asking a total stranger to dance. These are also the places where you'll see spontaneous performances, jams, and fun dance antics.
