Respect. My grandfather lived through his landing on D-Day. I have his letter from Eisenhower framed. From speaking to him when he was alive I still don't know if he was happy he lived through it or not.
RossUK, i understand. My father was in the Army Air Force, and he ended up on Okinawa, after the Marines secured it. As much as he knew how fascinated I was with WWII events, he would never talk about it. Neither did my 2 uncles. I did hear about 1 Uncle, who was a .50Cal gunner, about his mission attacking Germans holed up in a town in France. He gave me the 5 minute version. Done. Never wanted to talk about it again.
