We were walking back to the car after a visit to a nearby park. Zach found a little water puddle and started splashing in it. I thought, “Aw cute, I’ll get a photo.”” The next thing I knew he was sitting in it and had found the mud in the sidewalk cracks. He was so upset when I pulled him out of it to go back to the car. I just loved the way he was looking at the mud on his hands thinking — what is this??
