A famous doctor once received a little child that was badly

A famous doctor once received a little child that was badly ill. Thanks to his skill and care, the child got well and was soon able to get up and run about again.
The child’s mother was very thankful to the doctor, and she visited him for what he had done for her child. “Doctor,” she said, “you have saved my little son. I don’t know hoe to thank you enough. I feel that money alone cannot repay（回报）you, so I have made this little purse with my own hands, as a sign of my thanks. I hope you will accept（接受）it.” The doctor stood up and said coldly, “Madam, a little present like that is very nice between friends, but a doctor needs to paid enough for what he has done.” The lady was so surprised and hurt so much that she could not reply for a moment. Then she said quietly, “Perhaps you will tell me how much I should give you.”
“Fifty pounds,” he answered.
The lady opened the little purse and took out four fifty-pound bank notes. She passed one of them to the doctor, and put the other three back into the purse. She put the purse into her handbag and, saying goodbye to the doctor, went out of the room.
