The Mysterious Book...
Back in the late 1980s, my Dad was at one of those used book sales where someone sets up in a hotel ballroom with a bunch of tables covered with boxes of used books. Dad was wandering through, and a rather old hardcover book caught his eye. The writing on the spine is too faded to read, so he picked it up to look at it. Flipped it open, and found an inscription: "To Adele from Billy, on our wedding day, CityName, State 1936"
He'd found the book that my maternal grandfather had given to my maternal grandmother (Dad's PILs) as a wedding gift, in a city halfway across the country, 50 years prior. My grandparents were originally from the area in which my family lived when Dad found the book, but had been married in CityName due to Grandpa having to live there for work at the time, before they moved back a couple years later. Nobody knows when or how it vanished from their home, or how it ended up at that sale. Or why on earth this faded unreadable spine caught my Dad's eye.
