I have a hypothesis that 1/8 of fatherhood is treating the most interesting things about your life like a FOIA request is needed to get you to tell them.

My Dad may be almost 102, but let me assure you he is not confused. Also, Edward Teller was a good friend of my Dad and I remember him well.

My Dad worked with and knew many famous people like John von Neumann, Einstein, etc., so this anecdote was just another experience for him.

EDIT: I was saying that he was not confused about this story. I notice that my Dad is no longer as facile using computers. For years his hobby was writing screenplays, adding 3D animation, video segments of friends and family, and he had us all help with voices. He has mostly stopped doing that in the last year of two. I am not judging him at all: I am only in my 70s and I do much less technical work than I used to. My Dad has a saying: getting old sucks, but it beats the alternative.

Doesn’t seem unlikely at all based on his dad’s career/bio (see the Wikipedia page posted elsewhere in this thread).
