This happened quite a few years ago, before cell phones. I was on my way to work at the Aeronautical Center and stopped to help a lady. Her car broke down, it was parked off the road and she needed a ride to work at the Aeronautical Center. I did give her a ride. Some months later I was on my way to work and my axle broke. A car pulled up in back of me and guess what, it was the lady that I had given a ride to. Both times it was early in the morning and still dark. Sometimes things go around and come back.
