My Dad is 75, the very definition of curmudgeon.
He lives on the east coast and visits me a couple times a year.
He does not understand why I collect pinball machines, thinks its stupid.
I said, Dad, if you would just play one game with me, you would understand why I love these.
He absolutely refuses, says, "I have no interest in this whatsoever"
One of these days when he departs this planet I will buy a BBB and a MM on the very same day with his money, and not feel bad at all about doing it. Not for a second.
