It's not something we talked about, and we talked about everything. But not this. Not then. Not now. Not ever. Our imagined husbands might go off to fight a war someday, we said, and our sons, if we had sons, might someday be called to fight. We were, even as small children, familiar with battle. We'd read the poetry my father had written in combat. We'd watched "The Fighting Sullivans." But we never imagined the kind of war we're mired in now. We never anticipated raising a child and seeing him grown and married and settled, then suddenly unsettled and terrifyingly vulnerable. We never expected that at 35 he'd be called to serve.
