My friend and I both have young boys the same age, and we are also both balancing caring for our boys with our jobs. Once a week, we trade child watching duties so that the other can get a little focused work done.

On this particular day, I had both boys to watch. The boys have only recently started interacting with each other. I noticed them following one another around and happened to grab my camera just in time to catch them at the window, looking out at the snow and banging on the windowpanes together.
