I wonder sometimes if veterans are reluctant to share their experiences because they think no one today will care?
During WWII, one of my grandfathers was a Naval Gunnery instructor at Newport RI, and the other one flew B-24's, and was shot down over Germany, escaped, and was then interned in Switzerland. Niether of them ever told any stories. I only got the little I did from my one grandfather because one Easter in the 1980's at his club in Florida we ran into a guy who had been his tail gunner in his B-24, whom he hadn't seen since they bailed out over Germany. Diverse experiences, but they both, along with all the vets I've met since, seemed to move on and focus on what they were doing now
I recall when I first started shooting competitively, one of my mentors had been in the 82nd Airborne in Vietnam, and he kind of got up in my face. He told me that he had had to shoot "more than one person" and that it had been terrible, and to think long and hard about how I'd feel about that before I handled a firearm, every time, because accidents are worse and you can never take it back. It's hard to get across in print, but it was one of those slap across the face lessons for a young man, and I've never forgotten it, because I got the idea it was really important.
