When I was a kid, we had a neighbor that was a Marine Iwo Jima. He never said a word of it to his family.
His boys were the meanest mother scratchers ever. Like it was instinctive. Sucker punching, foul mouthed bastards. One of them called my mother "Mrs. Shit". LOL. Good people tho. Today we're good friends with his kids. He died a while back.
They must have been great neighbors.
