My dad used to say that the guys that talk the most are the guys that saw the least, and using that as the litmus test, this guy definitely saw nothing.
Sounds like my dad, he never talked about the war (WW2) until his last couple of years, and then only if asked.
He was part of a different generation; they knew how to suffer in silence. To bear their burdens without complaint. Somehow the later generations have never been taught this.
Motivational ping!
