My son and I went walking last night after a day of periodic rain. Most of the water had dried, but he found one puddle in the park, about the size of a salad plate. He worked that puddle: stomped it, splashed it, patted it with his hands, circled it, tapped it. That puddle just kept on. After about 5 minutes of solid puddle play, Ari seemed satisfied with the puddle’s veracity and we moved on down the path.
