One by one, other fathers joined in. Then mothers. The sound built, not loud enough to overwhelm, but steady enough to become a pulse. I stood at the edge of the floor with my hand still over my mouth and watched my daughter smile for the first time that night.

It wasn’t a tiny smile. It was startled, radiant, helpless as sunrise.

Halfway through the song, another Marine stepped forward from the line and approached a little girl at the edge of the room whose father, I suddenly realized, was deployed because she wore a yellow ribbon bracelet I had seen around school. He bent, asked her something, and when she nodded, led her onto the floor too. Then another fatherless girl joined. Then another. Within minutes the center of the gym had become something none of us had expected: not a rescue of only my daughter, but an expansion of the room to include every child who had come there carrying absence.
