You are so fortunate to still have your dad and more so, talking to him about his experiences.
My dad is gone now for 10 years. One of my biggest regrets is knowing little of what he did in WW2 and Korea. He was of the school that when you came home, you didn't talk of your experiences. That was "then". You got on with life and built a better world. And for 50 years he did just that, in his case practicing medicine, getting on with his life, the humble generation
Mine is 89. He still works most days. We often work together at the family farm. He was also a general contractor. Mostly residential, but did a fair amount of commercial projects. He was an artist at that.
He was here his entire life, except for his 2+ years in Europe in WWII.
Only time we talk about that period is where he and I see parallels today. He is a quiet modest man, has always been so. He had several friends who saw much worse duty than he did.
Family has owned/operated farms here since 1889. One of ancestors was born in “the Republic” of Texas.
