Lucy has done this twice now. She asks if we can make Jello and I say "Yes, but it will take it a long time to get cold. Remeber that we will have to leave it in the refrigerator for a long time before we can eat it." She leaves the room and when I'm ready to make it I call her into the kitchen. She pulls the little brown package of powder out of the refrigerator door and asks if it is ready.
