Milonga anyone?

So I´ve been learning lots of tango. It´s a bit hard on the ego as it a difficult dance to master. There are endless tango classes, shoe shops and shows here in Buenos Aires. For those who want to dance, they go to a Milonga. These usually start around 12am, any night of the week, and go till 4. Scratchy music, seemingly from an old phonograph, is piped into a large, stark room filled with tables, chairs, whirring fans and tangueroes in their best shoes. A request to dance is initiated by the men with a nod or glance from across the room but nothing more. No words, no gestures. One must scan the room constantly in order to catch someone´s eyes. But dare not dance unless you know how as only the best are rewarded with another dance.
