Wrong person, wrong street, but right broadcast

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.
