I had someone like that too. I worked at a gun store when I was 16-18, Gene was about 60. I learned more about life from him than maybe anyone. He was a master BSer. My favorite quote from him was in reference to the Vietnamese. "Bobert it's a F&$@ed up world 20 years ago I was paid to kill them, today I'm paid to wait on them." I kept in touch with gene for the next 20 years. I miss him a lot and think about him often when shooting or when I see one of his old guns in the safe.
I'm sorry for your loss.
May Gene and Paul both rest in peace.
