Every year I make a calendar full of family photos each month. Pictures from last February document a dinner out with friends, donuts sampling all over town, an overnight sleepover with a favorite family at the Field Museum. Living life without a second thought. When I flipped the month over to March, the photos show a sharp shift in content: No friends, no sleepovers, nothing but us at home.

As I turned the calendar, I thought about how I might commemorate this past year. I don't want to forget it, because it's an important time in our lives, but obviously, it's not an experience I ever hope to repeat.
