Although that might have been interesting to know about, I agree that the teacher should have worked with your body and movement as they are, not try to undo decades of habit ingrained in your normal walking. But then, that's my pet peeve with so many teachers... they don't take into account the typically unconditioned, middle-aged (or older), desk jockey bodies that so many social dancers come into tango with. (not talking of YOU DC). I've personally found this to be more true of young show dancers. They just can't relate. Although I have had dancers who perform work well with my body, and some older teachers who seemed more "social dance" oriented, oblivious. All this just proves that teaching is a different skill than dancing. I spend at least 1/2 of every private I take just walking. The longer I dance, the more focused I have become on walking. If I could focus on tango walking while sitting at the computer, I would!
