It's all good man.... what's important is that you love and appreciate him... let go of the regrets.
I stood in the American Cemetery at Normandy and cried till I had to walk away from the tour group... just couldn't help it. It's just very moving. My wife's grand dad rode a glider in to Normandy. Last thing he remembered from that day was tracer rounds coming through the floor and realizing the pilot shot was dead. He was one of three who survived the crash... broken pelvis, broken jaw... bullet wound in the arm.
He spent months and months in the hospital in England and then rejoined the 82nd just in time for the Bulge.... unreal.
He would never talk about it... even with his son who did a very tough tour in Vietnam. He was very old and I finally did get him to sit down with a map and a video recorder and I made a tape for his boys.
Greatest generation ever!
