Some ww2 vets were close mouthed. Did not want to talk about any thing. After I had been in the service Dad opened up to me. Seemed like he wanted someone to know. He never told my brother, non militwry, anything.
My Uncle Floyd was one of the toughest men you'd ever meet. He loved to fight and barroom fighting was his love. But he never talked about the war.
My Uncle John was wounded on one of the islands. Lost part of his skull and vision in his right eye. He was left handed and was quite the shot. Towards the end for him I asked about his service. It was like opening a book. He told me everything. I wrote his eulogy several years later and his kids asked how I knew all about their Dad. It was simple, I asked him.
When Dad and these 2 uncles were together they did not talk about the war. But they were tight because of their war experience. There was a bond from it.
