Here's something you always like to hear from your three-year-old.
We're at the playground. I walk over to him because he's approaching the broken water fountain. (It still dispenses water, but aberrantly because you've got to jab your finger into the hole that once had a button, and unless you cover the whole thing it squirts in your face.)
I ask him, "Are you really thirsty or do you just want to play with the water?"
He has a sheepish look on his face and I think, "Got you now, hunh, Mister?"
Then he answers, "I dinna go poo-poo on myself."
(I'd leave it at that but I know some of you have a need to know. He really didn't.)
