Generosity

It's hard to dance tango if you're selfish.  It's also easy to have selfish moments when you're at a milonga.  Perhaps it's even necessary to have those moments.  Otherwise, we'd all be perpetually beholden to those who use guilt as an alternative to the cabeceo.

At some point between selfishly avoiding eye contact with those we don't want to dance with at the moment, and taking up the embrace to dance with somebody we do want to dance with right now, we have to switch off from 'me' mode and switch into 'she' or 'he' mode.

The best amongst us can bring this generosity to bear on almost every partner they dance with.

The very best can even do so with the selfish ones.
