Me: "R., why are you washing dishes?"

One evening I was visiting a lovely older British friend of mine for his birthday party. He had a new Thai bf at the time. As the party wound down and everyone left, it became obvious it was time for cleanup- and my friend started cleaning up the place.

Me: "R., why are you washing dishes?"
R.: "You know, that's a very good question."
Me: "Sit down."

At which point *I* started cleaning up the place. It was another 10 minutes or so before I think R.'s bf realized that he shouldn't have been letting R. do the work, and he rushed over and took *my* place at dishwashing. I don't know if that's any clear sign or not of how things stand in a relationship, but soon afterwards the two of them broke up.
