" Are you angry, El-ahrairah?’ asked Lord Frith. “‘No, my lord,’ replied El-ahrairah, ‘I am not angry. But I have learned that with creatures one loves, suffering is not the only thing for which one may pity them. A rabbit who does not know when a gift has made him safe is poorer than a slug, even though he may think otherwise himself. "
