Yesterday, I stepped into a shop to have my watch repair. After the shop assistant checked the watch, she said she had to contact with her manager to see if this kind of problem could be fixed. As I was waiting the response from the manager, I saw a old man in a wheelchair roll himself over to the counter. No one seemed to have noticed him, so I got up, went over to his wheelchair and ask whether I could give him some helps. Kindly as I was, I found that I could do nothing to help her. At that moment, the assistant replied that it would cost little money to fix this problem. I was very sad and about to leave the shop while the old man said, “You are a nice and thoughtful boy, and I would like to help you pay for it.”
