I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do.A car pulled up behind me.It was the couple. They said they would take me.We chatted and when I got out of the car, the husband gave me his business card.I wrote them a thankyou note.Soon afterward, I received a Christmas present from them.Their note that came with it said that helping me had made their holidays meaningful. Years later, I drove to a meeting in the morning.In the late afternoon I found that Id left the lights on all day, and the battery was dead.Then I noticed that the Friendly Ford dealership was right next door.I walked over and found two salesmen in the showroom. “Just how friendly is Friendly Ford？” I asked and explained my trouble.They quickly drove a pickup truck to my car and started it.They would accept no payment, so later, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever written him to say “thank you”， and it meant a lot, he said. “Thank you” — two powerful words. Theyre easy to say and mean so much.
