You weren't just learning to dance — you were learning to "man" and to "woman." It's a relic. And in the way of relics, you don't throw it out, but you need to know that this is the past.
Uno no solo aprendía a bailar, aprendía a ser "hombre" y "mujer". Es una reliquia. Y como toda reliquia, no se la desecha, pero hay que saber que es el pasado.
