This is a good one, John. Thanks.
I, too, enjoy thrift stores. I had never thought about these analogies that you mention. They sure do ring true for me.
About fifteen months ago, at the age of 76, I made a new friend through an organization we both belong to; she is about two years younger than I.
Over the last year, we have become very good friends who regularly share two activities a week. In fact, we have become such good friends that my partner refers to her as my "girlfriend," which we both think is hilarious.
