If there's anyone not already at "that age", at some point many/most people start reading the obituary section, "To see if I'm in there!"
Age, natural selection, bad luck all take a toll.
There are a number of people I knew in high school that I have lost track of, and have been curious about. Last week I saw an obituary for an older woman with the same last name as a "missing" friend. Indeed it was his mother, and, sadly, he was listed as having predeceased her.
His parents had been missionaries. He was in the journalism clique, although I knew him from band. He had convinced a local church to let him set up a weekend coffee house in the basement. I spent a lot of time there helping with this and that. It was there,after closing one night, that we got robbed at gunpoint. I had 4 quarters, which got dropped by the gunman, and I retrieved. But it went into the report and I got repaid a year or so later. The gunman was an AWOL airman from the local base. The gun, BTW, was a .22 pistol that looked like a shotgun to me! I met a lot of interesting people and had some very interesting experiences there.
We had hung around together a few years in high school, but by senior year he had lost interest in our friendship it seemed. The last time I saw him was immediately after our graduation ceremony when I called out to him. He waved and said "catch you later". I never saw or heard from or about him again.
I posted a message on Facebook asking if anyone had any info, and one classmate responded that he had killed himself in the early or mid 70's.
