"The fish is my friend too," he said aloud. "I have never seen or heard of such a fish. But I must kill him. I am glad we do not have to try to kill the stars." Imagine if each day a man must try to kill the moon, he thought. The moon runs away. But imagine if a man each day should have to try to kill the sun? We were born lucky, he thought. Then he was sorry for the great fish that had nothing to eat and his determination to kill him never relaxed in his sorrow for him. How many people will he feed, he thought. But are they worthy to eat him? No, of course not. There is no one worthy of eating him from the manner of his behaviour and his great dignity.
