Sometimes, invariably at the barre, the teacher will show a combination and it all looks simple enough. UNTIL. Until someone has a question about it, and the answer confuses someone else, and the explanation of the answer confuses the first person again plus four or five other people. And the teacher says "okay, enough! Let's just do it and see what happens!" and someone who is More Serious Than You argues that without understanding the proper choreography the entire thing is wasted... and by the time we actually get around to attempting the silly thing no one has any idea what is going on. EVEN THE TEACHER. And now everyone at the barre is doing something different and all you can hope for is a quick transition to the next exercise. Because DAMN.
