"Good morning, Eeyore," said Pooh. "Good morning, Pooh Bear," said Eeyore gloomily. "If it is a good morning, which I doubt," said he. "Why, what's the matter?" "Nothing, Pooh Bear, nothing. We can't all, and some of us don't. That's all there is to it." "Can't all what?" said Pooh, rubbing his nose. "Gaiety. Song-and-dance. Here we go round the mulberry bush."
