You need a jump? Pay it forward, he said, and I did

My car would not start in The Heights on Sunday morning and I was standing there with the hood up like I knew what I was looking at. A man walking by asked, you need a jump? Four minutes later it was running. He refused money and just said, pay it forward. Two weeks later I did it for a woman outside a grocery store. She said the same thing back. I have no idea how far it has gone. I would like to meet the sixth person.
