A Code of Tango Etiquette

when you (fancy yourself to be) "the better dancer"

when you (fancy yourself to be) "the poorer dancer"

when you really don't want to dance

asking a lady to dance with you

asking a gentleman for a dance (or, asking by not-asking)

explanations - a useful habit

accepting dances you don't want

when you refuse a dance (ladies)

the "three-to-one" rule
and, exception to the "three-to-one" rule

duty dances

why do we use codes, anyway? why not just say what we mean and mean what we say?
well, apparently there are real sociolinguistic reasons why etiquette exists in the first place.
