As I mentionned in another topic, I think men shouldn't try to impress us ladies with all their moves in just a song - especially if they should notice that the woman is not proficient enough to follow what they lead.

I was in a Milonga recently where I observed two interesting things.

a) I danced with a man who during the first 1 or 2 songs did very minimal dancing and a lot of pauses (fitting with the music). It was however clear that this was not because he was a beginner but he did it on purpose. It was kind of fascinating. Then he slowly built up and added more and more moves and steps.
I never felt under pressure to "run along" and it was a really good experience.
Something I would suggest you to try!

b) There was an elderly couple and as it seemed the lady was not at the same level as her partner, although they danced together a lot. He was constantly doing wild stuff and she was struggling sooo hard to follow.
It looked as if he had a lot of dance experience and wanted to teach her all he knew (yes, teaching on a Milonga dancefloor, baaaaad manners!) in one night.
The poor woman was clearly overhelmed and if I may say, some of the movements were just to hard (physically) for an untrained lady over 50....
It did NOT look like fun, I rather pitied her.
I do not suggest to try this....

Any more experiences/observations?
