Teaching at the Milonga
It seems like this has been covered before on nearly every tango blog, yet it always surprises me to see it happen at milongas. There were three instances this weekend. *sigh*
A few words of advice for dancers that feel the need to teach at the milonga . . .
Leaders: Don't assume that if a follower doesn't follow something you led, that she doesn't know how to follow it. To be clear, that doesn't mean you need to assume you led it wrong - there could be other reasons she chose not to follow it (there wasn't room, it was uncomfortable, skirt was too tight/short etc.) To take those instances of a lead being missed, or ignored, as a "teaching moment" at a milonga, may find you getting a lot of averted eyes the next time you look for a dance.
And really, if a leader has to explain a step to get a follower to follow it, there are already problems. The follower wasn't ready to be led the step, or wasn't in a position to follow it for whatever reason and explaining it verbally, in front of others at a milonga, worsens the problem and puts your reputation as a desirable leader on thin ice.
Followers: The same goes for us. Unless a leader is painful or uncomfortable (emotionally or physically), to follow, it is not okay for us to teach at the milonga either.
Teaching, or worse, reprimanding a dancer over mis-followed or mis-led steps, doesn't make you look smart, it makes you look like a jerk.
