This is the story of a foolish boy

There were three friends in a village. One of them was very intelligent, and second of them was middle class not more intelligent and more foolish, but third of them was very foolish. One day they thought to go out side for a while. They got ready and began to walk until they reached a historical place they watched so many things like they watched some buildings which are very old, and they watched some elephants felt very happy. Suddenly they watched a waterfall which was very impressive and water was very clean. They decided who will go down first into water the third who was very foolish said I will go down first into water. He went down into water began to swim the water was very cold after five or six minutes he came out from the water. His two friends said him why did you come out from the water then the foolish man said the water is very cold so I didn't take bath more as he said the water is very cold they began to laugh and lastly said that's why we didn't go into the water and call you to go into the water and you went down.
