I discussed this with my father yesterday, as he came to my house for a few items stored here.
We ended up having a conversation that danced around my abandonment of a seemingly brilliant career, as well as his very significant role in world-supply of food and armament.
I really have no regrets in not being able to go back to that world as its simply not an option. Its not a choice. Its a condition of reality. But he has always been hyper-sensitive to time passage.
Again...no regrets here regarding my use of my time. I think I did more than could have been expected. I have a LOT of life's substance to look-back upon, as does he.
I hope some of my positioning served to quell his thoughts that I'm pissing my life away...that right now, I'm just trying to exist...and that's good enough right now.
Je Suis Charlie!
