How I knew I had the right one 20 years ago:
I was in Government Center in Boston with Gigi Harris before we were married. Strangely, the crowd cleared and suddenly it seemed as though Gigi and I were walking alone; except for one homeless guy, just ahead sitting on the ground with a hood pulled over his head.
As we approached, we could not see his face; but just as we passed by, without even looking up he said:
“If you don’t marry her, I will.”
We were shocked, and kept walking. Moments later, we turned around…
But he was gone.
