    A great French writer has said that we should help everyone as much as we can because we often need

help ourselves. The small even help the great.About this, he told the following story.

    An ant was drinking at a small river and fell in. She tried her best to reach the side, but she couldn't move

at all. The poor ant got too tired but was still doing her best when a big bird saw her. With a pity, the bird

threw a piece of wood. With it the ant reached the bank again. While she was resting and drying herself in

grass she heard a man coming up. He was walking without shoes on his feet and carrying a gun in his hand.

As son as he saw the bird, he wished to kill her, and he would certainly do soon, but the ant bit him in one of his

feet and at that moment the bird flew away at once. It was an animal mucher weaker and smaller than the bird

herself that had saved her life.
