Why are you chasing your tail so?" Said the kitten, "I have learned that the best thing for a cat is happiness, and that happiness is my tail. Therefore, I am chasing it: and when I catch it. I shall have happiness." Said the cat, "My son, I, too, have paid attention to the problems of the universe. I, too, have judged that happiness is in my tail. But, I have noticed that whenever I chase it, it keeps running away from me, and when I go about my business, it just seems to come after me wherever I go.
