Diana was a chemical teacher. She taught her students something like lime could be obtained by burning limestone. One night she saw a dog lie under a tree when she was passing by. It was too weak to lift its limp paws. It was likely to be hurt by the fallen limb. Diana knew her limitations. In the light of her mother's comments, her love had no limit. In fact, there was much likeness between her mother and her. Diana held the dog in her arms. The dog licked her hand. Its head touched her shoulder lightly. Diana went to a hospital. Only a limited number of hospitals were available to animals. A full moon lightened their path to the hospital. The doctor said the problem lied in its forelimb and it would not die. Diana's heart lightened when she heard it. Two weeks later, the dog could walk with a limp. One day, there was some likelihood of rain. In a lift, Diana met a man who asked her if she had a cigarette lighter. The man approached her and suddenly he took out a dagger, "Give me your purse!" Just then, the dog jumped at a lightning speed. It bit his wrist. The man cried and rushed out of the lift. Diana would remember this during her lifetime. The dog cast light on her of its love. The dog never lied, and it even saved her from danger. When they returned home, to reward the dog, Diana lifted the lid of the lot and took out a big bone for him.
