Once an old lady lost her eyesight and became blind. She called a doctor and agreed to pay him a very big amount if he cured her.
But she will not give a single penny if she is not cured. Doctor daily came to her house for treatment. He started stealing lady's furniture and other valuable things from the house. He took away everyday one thing from lady's house.
So he delayed curing the lady. He cured the lady after he had took away all the furniture and valuable articles from the lady's house.
Now doctor demanded his fee from the lady. But she refused to pay the fees and said that she is not fully cured. Doctor registered a case against her in the court. On being asked by the judge why she was not paying the fee, she told the court that her eye sight is not fully restored.
She could not see her furniture and other articles in the house. The judge was very clever. He understood the matter and punished the doctor.
