A good friend of my wife once did this to me at a wedding. She had started a pair dancing hobby maybe six months earlier and was very enthusiastic about it. When I asked her to dance, I didn’t mean I wanted a lesson. It was so out of sync with my expectations that I left with barely an excuse in the middle of the song.
I just remembered I did recently ask someone to teach me a dance ("just off" the social floor), but 1) it was in a crowded bar just off the dance floor so it's less in the way than the onlookers 2) it is a notoriously easy dance 3) she knew I was good at dance 4) I picked it up in 45 seconds 5) we immediately went on to the dance floor and finished the song together with no further instruction.
