I think that joke must be pretty universal (en France : non, l'autre main gauche ! ).
The thing is that we can joke about each other's mistakes and still get some good dancing and enjoy ourselves. It's a matter of cooperation and team work, not competition to see who is best.

It is also great to be able to travel somewhere new, find a SCD group, join in and feel you are among friends. I was very glad to find SCDers when I went to study in N Carolina many years ago, and, more recently, I have been welcomed into clubs in Germany, Austria, Hungary, Japan, and now, in Spain.
