W. and I were at the warehouse store yesterday evening. A woman was near us in the aisle, and her kids were fooling around in the cart. One of them was standing up and leaning over, and she reached forward and popped him on the bottom. He said ouch!, and she commented, "That's what happens when you stick your butt out!"
We walked around the corner, and since there was no one in the aisle at that moment, I stuck my own butt out as I pushed the cart. W. gave me a smack, and said, "That's what happens when you stick your butt out!"
That smack stung more than I expected, because two days down the road, my bottom was still a little tender from our usual Sunday night spanking. (Two and a half days later, I can still feel it, actually!)
