This is a really interesting article - it did capture the several aspects of social dance and it's attendant connotations. But it left two out, in my opinion.
Before I was married I adored social dancing and used to go often. Either with a date or with a girlfriend we would go and have a great time. Perhaps meet someone of the opposite sex (or not), it was not only fun to dance but fun to just get to talk to different people my age.
Several years ago I accompanied several women to a club - a 'scene' I hadn't visited for decades. I didn't go to dance, just to accompany these female friends. Two things struck me. First of all, as one looked out onto the dance floor it was impossible to tell who was dancing with whom. No one dancer seemed to be focused on a partner. And they didn't seem to care.
The second thing was the volume level. Speech was impossible. Utterly impossible. I couldn't have held a conversation with myself and heard myself talking. This puzzled me. So, after getting home I had a conversation with my son, who at the time was 'club scene age.' The conversation went something like this:
Me: "When you go to a club, isn't meeting someone one of your goals?"
Me: "How can you possibly hold even a simple conversation like 'what's your name?' with that level of noise?"
Him: "You can't."
Me: "If you see a pretty girl and you ask (it would have to be mime) her to dance...don't you want to know her name?"
Me: "Doesn't it bother you that the music is to loud to speak to her?"
(he wasn't always this monosyllabic)
