Better Luck Next Year
I once bought my kid a set of batteries for Christmas with a note on it saying “Toys not included.”
Unexpected guests were on the way, and my mother, an impeccable housekeeper, rushed around straightening up. She put my father and brother to work cleaning the guest bathroom. Later, when she went to inspect it, she was surprised that the once-cluttered room had been tidied up so quickly. Then she saw the note on the closed shower curtains. It read "Thank you for not looking in the bathtub."
