After I posted "Remember where you were when you heard…" I started thinking about the Wikipedia entry on Lillian Hellman. The broadcast about the famous person's death mentioned her sister, but the Wikipedia entry on Lillian Hellman didn't mention a sister. Then I realized I was thinking about Lillian Gish. Then I started to rethink my location when I heard the broadcast. The Crystal Post Office was not on 42nd Street but Bass Lake Road east of Broadway.
But my short-term memory is failing me more and more. This morning I could think of the first names of a couple we sat with at a church dinner last night but I couldn't remember their last name. And we've known them for years. I won't go into the details, but a mundane set of unrelated observations set up the link in my head to their last names.
