My dad drove me to the store to get some food and drink for dinner. It was for a new customer who was very important for his company.
As we drove, we noticed an old man at the side of the road. His 1 didn't work. My dad would stop 2 , but he didn't. He said, "We are too busy right now. "
About half an hour later, when we were driving back home, we saw the old man still working on the car 3 . This time, my dad stopped his car without 4 .
"Anything I can help?" he asked.
"Yes," said the old man. "I can't get the wheel off. No one has come to help me. You are the 5 person stopping to offer help. "
My dad had the 6 wheel off and the new on. The old man offered to pay us, but my dad 7 . At about 6 pm, my father was very 8 because he has not met the new customer before. Then the doorbell rang, and my father answered the door. My father's face went white. It was the old man he helped!
The old man could not believe his eyes. He said, "You're a man with a kind heart. You're a good example for your son. I'm happy your company has 9 business. "
Of course, my dad didn't help a 10 to be rewarded(酬谢). When we do the right things, the right thing happens to us.
