My dad is now 95 and a WW2 Army vet in Europe. He was wounded in action and therefore earned a Purple Heart. He never spoke of the war - came home, went to college on GI Bill, married, had me, worked for 30+ years at same job as a Chemist for a research facility for Pulp and Paper, and served as a deacon of our church.
He neither encouraged or discouraged my Army career but I could tell he was proud of my accomplishments. He spoke more about WW2 than I ever had heard before the night I came home from my Iraq deployment.
Mom passed at 92 and we recently brought dad to the best assisted living facility we could find close to us - he now has some memory issues. In cleaning out the family home; I found his military awards including the Purple Heart and a small old box with the bullet they removed from his leg plus his WW2 era class A's with 4ID shoulder patch. He still gets some VA Disability for his wound plus complications from frostbite.
Truly - the Greatest Generation.
