So I spent 15 minutes of my 30 minute group lesson practicing two foot spins. I had a couple that were stable and nicely centered. But, hey, I'm elderly, I've got inner ear issues. At first I was dizzy, then suddenly:
Tener mal cuerpo!
I just clung to the boards for a couple of minutes and frantically waved the coach away.
("Please, dear god, don't let me hurl over someone's boots.")
