Your posts here have been so right on that I really do not want this common misconception to tarnish them. Though, I agree that what you posted occurs far, far too often...I like to say that one partner could drop dead and the other would finish the dance w/o him/her...this is, for good [real] dancers, not the case even in a structured dance. For these persons, even though they are dancing a prescribed pattern, the ability to lead/follow the nuances of the movement/s; rhythm/s, timing/s, styling/s, etc. are very present. I have judged 2 couples (supposedly of the same pro status) dancing exactly the same movements side by side, and at the same time, whereas one couple looked as though they were walking by the numbers, and the other was dancing.
