To every mother who didn't know it was the last hug, to every father who squinted back stinging tears, to every brother and sister, thank you. To every husband and every wife, who held a perfectly folded-triangular flag in one arm and a child in the other, thank you. To every best friend who remembers the last beer, the last fishing trip, the last football game, thank you. And for every child who knew his mom or dad only by the stories they’ve been told, thank you. To everyone who loved someone who paid the ultimate price, thank you.
