Many years ago, I owned a service station and roadhouse on the main road between Melbourne and Adelaide.

One very cold, wet night at about 3:30 a.m., there was a   36   on the front door of our house. A young man, wet from   37   to toe, explained that he had    38   out of petrol about 30 km up the road. He had left his pregnant wife and his two children   39   at the car and said that he would hitchhike(搭便车) back.

Once I had    40    a can with petrol, I took him back to his car where his two-year-old and four-year-old children were both    41  , saying that they were cold. Once the car had started, I suggested that he   42   me back.

Before leaving, I had turned the heater   43   in the roadhouse, so that when we went in, it was nice and   44   .While the little ones played and ran   45   ,I prepared bread and butter for the children, and hot chocolate for the   46   .

It was about 5 a.m. before they    47   .The young fellow asked me how much he   48   me and I told him that the petrol pump had    49   $15.He offered to pay “call-out fee”, but I wouldn’t accept it.

About a month later, I received a   50    from Interstate, a large bus company that we had been trying to   51   to stop off at our roadhouse for a long time. It   52   out that the young fellow I had helped was its general manager, the most   53   person in the company.

In his letter, he thanked me again and    54   me that, from then on, all their buses would stop at my service station. In this   55   ,a little bit of kindness was rewarded with a huge amount of benefits.
