“Wolves” and sheep

A:  I don't know that I have nerve like that. Going where I knew I wouldn't be wanted. They couldn't want you for your dancing without the worry about what you might say to their students. It would be against instincts of self-preservation. It would be like letting in the wolf, without the sheep's clothing.

B:  It depends whether the area has a competitive market, how insular it is, how defensive the teachers. In some places the balance of cost/benefit is more likely to be in favour of just getting people who can dance. Class-teacher organisers in competitive markets like e.g. London are really sensitive to the effect of people who can actually dance going only to the competitor's milonga. Some teacher-run milongas would rather have their own classeros dance with classeros of another teacher rather than have non-classeros coming in.

A:  So which is it - they welcome people who can dance or they try to keep them out because it makes class people look bad?

B:  They want people who can dance - who may or may not be classeros - provided those people a) don't show up their class students (and ideally can be mistaken as class students of theirs), and b) do dance with their class students.

A:  So are you saying now that classeros can dance?

B:  No. But I'd say a few can. 

A:  I'd agree with that. But more girls than guys. And that's mostly because they just pick it up not because they learn it in class. Whereas more guys "think dance" than girls, which is a class legacy.
