I post this with current variations every year.
My father and 3 friends were at the Giants game when the Pearl Harbor attack occurred. It was announced at the game. The next day all 4 enlisted. My father landed in Normandy during the D day invasion. Up to the day he passed he spoke very little if it all about the experience. He shunned any gratitude given him except to say the true heroes were the ones who did not return. The WW II vets returned home, went to work raised families and went about their business. Many suffered in silence. At the age of 90 my father was diagnosed with PTSD. He very rarely let on to us anything was wrong. It wasn't until my youngest son enlisted that he finally spoke, only to him, about some of his war experiences. My son to his credit will not tell any of us what he said as that was my father's wishes. Many of my friends who have veteran father's tell similar stories. They were truly our greatest generation.
My son is expected to return home from a middle east tour soon and we could not be prouder and more thankful of him and all those he serves with.
