My daughter and I were playing Connect Four yesterday afternoon. She was about to drop one of her pieces when I told her that I saw a spot where she could win. She examined the board, but couldn't find the spot.
I said "Look closely."
She got right down on her hands and knees and put her face about two inches from the game. She didn't understand why I was laughing.
There's not a whole lot of edgy or sophisticated humor in our house, but there is plenty of genuine laughter.
