Once upon a time, a scorpion lived in a dark cave near a mountain. He was not happy with his surroundings at all. One day, he came out of his cave and noticed that the valley across the river was very green. Suddenly, he saw a frog leaping around. He asked the frog, “Hello, Mr. Frog! Would you carry me to the other side of the river?” The frog replied, “No, I will not. I do not trust scorpions.” But the scorpion pleaded, “I do not know how to swim. So, if I sting you on the way, I will also die.” The frog was convinced and carried the scorpion across the river. Half way through the journey, the scorpion stung the frog. “Why did you sting me? Now both of us will die,” cried the frog. The shameless scorpion replied, “There is nothing I can do. This is my nature. One cannot change one’s basic nature.” And both of them got drowned in the water.
