A Farmer and A Snake
Once there was a farmer. One day he was returning home in a cold evening. He saw a snake on the path. It was almost frozen with cold. He took it home. He put the snake near the fire. It got warmth and revived. The farmer gave it milk. It started moving. His child was playing there. It tried to bite the child. The farmer got furious. He killed it with a stick.
