Total strangers often have surprising connections to us if we're open to them. They've happened so often to me that I'm not just open - I expect them and am delighted when they happen.
Several years ago, a buyer found me on the internet and called from California, about to take a job in Kingsport and not sure whether they'd want to live in Johnson City or Kingsport. In the course of getting acquainted, I discovered that he had grown up not just in Johnson City, but in Towne Acres, which is the "generic" name for several small subdivisions that are near Towne Acres Elementary School.
"I live there now," I told him. His folks still live on Willmar, his story continued. "That's in walking distance of my house - I walk down Willmar almost every day." I didn't tell him, but many of the people on Willmar are on my neighborhood email list and I know several of them personally.
We finally got around to discovering that his folks lived in one of my favorite houses, and that his mom, Nancy Beach, was a dear friend.
All this was going on in late June of that year, and I invited his family and his local family to come to come to our hill to watch the fireworks. That's when we discovered that he already knew my hill - he'd watched fireworks from this hill before my house was here, which makes it at least a 20+ year tradition. They came, they live in Kingsport, and they'll probably come again next year.
I'd be delighted if you'd share your serendipities with me. I think there's a book in me somewhere.
