...this exquisite summary of social dance culture. It's partially a tutorial in etiquette, a topic that I happen to find fascinating and quite diverting, but that some feel is rather dry. More importantly, it seeks to define the more elusive qualities that define the happiest, most in-demand, and best social dancers (hint: it's not extensive training or the ability to execute complicated steps).
If I ever am in a position to teach social dance again, I think this treatise shall be required reading prior to the first lesson. Delightful!
