Whenever I have guests for dinner, I tell then when it is time to end the event. Either I sense there is no more to talk about, or I am tired and ready to have them leave so I can do dishes and clean up. My friends like this. No one is ever concerned about staying too long.
I had a party. There were 24 people in the house. One friend asked if it was time to leave, being cute. I said it was not my choice this evening. My 14-year-old grandson was there. He knows nothing about my ritual. I said, “Isaac, is it time for the guests to leave?” He was engaged in conversation with someone at the time. He looked at his watch and said, “Not yet.” I asked him when they should leave and he said, “7:15.” I asked him the current time and he said “7:10.”
My friends all laughed and suggested Isaac and I are related.
