Tonight, as we were putting the kids to bed, Alice decisively left the room, shutting the door. She immediately came back in, saying: “I am the King of Yumminess! No more laughing!” Then she left the room, and repeated several times. Each time, with a different delivery, and instructions for our response, like an actor riffing on lines and a director giving notes to actors.
It got so that she had all of us leaving the room and coming in again with variations on the King of Yumminess. (King, Queen, Prince, etc.) Needless to say, we were all laughing a lot.
