2-hand turns -- one year I was teaching a dance that had a 2-hand turn -- which I discovered was beyond their comprehension. Lots of blank faces and a few tried to hold onto each other and turn under their own arches. I grabbed a young fellow close by and demonstrated a 2-hand turn and there was a huge "ahhhh" from the group. Who'd have thought that was a foreign term for 18-year olds. Why don't they teach this stuff in school anymore?
