Alan, he sounds like he had a full life. We live in a different world the what our fathers lived in. If I remember correctly you and him had a face to face on a visit and told him what was on your heart and apologized. You love him that’s what’s important. It’s just important to care and love him and in sickness he is blessed in a home a great view and a loving family. Don’t let the devil make you feel guilt.
could you find some old tractor books for him. Maybe some books o life in his generation. Just trying to help. I feel for you and at one time we have much in common. God bless you..
