    Jackson was driving back home along a road one evening. He just lost his job. It was winter and it was very

cold, just like his feelings.

    An old lady with her car was standing on one side of the road. She needed help. No one stopped to help her.

Jackson stopped in front of her and got out of his car. The lady looked very worried. Even when he put a smile

on his face, the old lady still looked worried. Was he going to hurt her? He didn't look safe, and he looked poor

and hungry. Jackson knew how she felt. He said." I'm here to help you, madam. Why don't you wait in my car?

By the way, my name is Jackson."

     The lady thought for a while and then went into his car. There was something wrong with her car. Jackson

went under her car to repair it. When he finished, he got dirty and his hands hurt. Then the lady told him that

her name was Anie. She asked Jackson how much she should pay for his help.

    Jackson never thought about getting money. This was not a job to him. This was helping someone in need.

He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she

should give that person help.
