Elevator Etiquette

This morning, I took Silvie to her preschool. While we were in the elevator, she looked at me and said, "don't put your foot in the door." I said, "o.k."

Then she said, "and don't put your hand in the door, it might get caught." I said, "you're right."

Right before the elevator got to the ground floor she said, "and no peeing in the elevator!"
