I told them "Sweetie, it's normal for depressed parents to get up in the middle of the night and eat a huge slice of chocolate cake. Go back to bed. No you can't have any."
My back was to the door and we were still covered. 11 yr old daughter opens the door presumably to say goodnight and stands there in the dark. I turned and said, “goodnight!” She just backed out and shut the door. We went on about our business. Lol.
