Yup. Hard times produce formidable souls.
My Dad never said a word about it. He went to european theater...first i ever heard about his service was by accident. As a teenager visiting relatives one of my Dads childhood friends pulled me aside and told me 'hey, u kno your Dads a hero? Do you kno wat he did in the war?'
My Dad was in earshot and stopped the story telling.
Social media would have failed miserably in previous generations when people valued modesty and privacy above self exposure.
