It was raining hard and nearly dark. I was late for an appointment（预约）in a nearby city that I know only by GPS. And now my phone has died. The usual exits（出口）were closed. I didn't know how to get where I was going or how to let my appointment know I might not make it there.
I stopped at a KFC in a poor part of town and walked up to a mother and her teen daughter.
“I'm sorry, but is it possible for me to look up a number on your phone and then call the place and let them know I'm lost?" She handed me her phone and then told me I was lucky she had her phone, for it was getting ready to be turned off because she didn't have enough money to pay the phone bill.
The young girl and the mother didn't pay me much attention when I made a call. The appointment told me how to get there by another road.
Before I left, suddenly, I reached into my wallet where I don't usually have cash（现金）and pulled out all I had, a $20 bill. I gave it into the mother's hand and then turned to leave quickly. I heard her daughter calling after me, "Thanks, sir. You have no idea how you just helped us. "And yet, they really helped me.
