The fool came to the bottom of the cliff. He didn't realize it was a dead end. He wanted to go up, so he jumped. Jump, jump, jump, up in the air, up the wall. The wall gave him the strength to bang his head against the other wall. He held the wound, but laughed. "Hey, this is a good way to go! " He said. "I will go this way! " He jumped, jumping back and forth between two walls. He broke his head, but gradually mastered the art of jumping. "How lucky I am. I will soon be up there! " Happily, he charged again. But this time, luck didn't favor him. The moment he saw the top of the cliff, he fell. Like a bird without wings.
