Today's OneWord: Grandfather

My grandfather had fought in two wars: World War II and the Korean War. After that, he was never exactly the same. Not in a bad way, though; somehow, being a soldier had opened him up in a lot of ways, so instead of trying to appear aloof and macho, he was emotional, sympathetic, and quite the storyteller. Of course, there were nights when my grandmother would catch him awake very late, staring out the window, singing a song to himself from way back.
