Flippy Cup
(My sister has been the only one home for several days. When I go to get a cup from the cupboard, they are all flipped upside down.)
Me: “Why are all the cups like this?”
Sister: “I don’t know.”
Me: “How could anyone else have done it? You didn’t have friends over, did you?”
Sister: “No, I did it. I just don’t know why.”
