During the lesson, we will work a bit on floorcraft as well. There are a few social niceties that need to be observed in order for everyone to dance comfortably (and safely).
Specifically: dance your progressive dances (Waltz, Tango, Foxtrot, etc) counter-clockwise around the room. Keep to the middle and stay out of the corners if you are trying to find a "safe zone." The outside track is for fast traffic.
For dances like Hustle and most forms of swing, do not hog the whole floor with your patterns. Rein in the arms, take smaller steps and watch out for other people.
