I admire Emily Gurnon's Pioneer Press piece about her parents and their WW II courtship.
So many of these stories end with the man coming home safe to his patient sweetheart and starting a family and everything is peaches and cream from then on. This story is blunter, and more honest.
And here is another piece that gets at the same point, through a scrapbook that a British blogger found. In most stories, it would have just catalogued the happy times (and dog-show fascination) of an ordinary couple. But this story packs a punch.
Both these links are really worth a lead. These are the stories Hollywood doesn't tell.
