Every Memorial Day, I take out a scrapbook my grandmother made over 40 years ago. Each page is filled with headshots of young men with stiff Air Force hats clamped to their heads, their newly-buzzed hair just visible above formal collars. Some gaze at the camera confidently, their broad shoulders filling the frame, while others appear too young for the uniforms buttoned around their necks. Under every face is the exhortation: WHERE IS HE? My uncle’s face is on page three.
