I recently changed my dance schedule to go to a Saturday morning practica followed a few hours later to a milonga. The practica rules are different or seem to be different from those of a milonga. There's no teaching or commenting at a milonga, but what about a practica? I'm short and find it very difficult to dance with women with wide frames, stretching my arms. Some women ask for advice so I can comment to relax their frame. As an example, I throw their right arm over my shoulder so now they can't push me to their side. Most notice a distinct improvement in their dancing because they can better hold their balance. But what about those who don't ask for advice. The rule at the milonga seems to be "You invited her so stink it up for a tanda." Is that the same rule at the practica? I don't want to hurt a woman's feelings but then, I don't want to get hurt. Last Saturday, I just had to tell a woman that she was missing every pivot because she wasn't keeping her feet together and couldn't get her weight onto one foot. What is the etiquette at a practica? Is there any etiquette. I've seen men teach for at least 30 minutes to the SAME woman. That's not what I want to do.
