OK. It just occurred to me that the changes in communication technology is incredible. Do you remember hearing anything about the way the Pony Express was such an improvement in getting the mail through?
I think that I read somewhere that letters used to take months to get from the frontier back to the East. Now we are having a conversation in real time. AMAZING!
He was amazed that he could pick up a phone and call someone half way across the world, book a flight and go there in mere hours, know what had happened in the world on the same day it happened, through radio, and TV.

He was comparing all the changes he had seen, and how lucky he was to witness it.
It was a great conversation. I wish I had been older so I could remember more of it.
