Here is Edward Bear, coming downstairs now, bump, bump, bump, on the back of his head behind Christopher Robin. It is, as far as he knows, the only way of coming downstairs, but sometimes he feeld that there really is another way, if only he could stop bumping for a moment and think of it. And then he feels that perhaps there isn't. Anyhow, here he is at the bottom, and ready to be introduced to you. Winnie-the-Pooh.
Taken from "In which We are introduced to Winnie-the-Pooh and some Bees, and the Stories begin"
"So did I," said Christopher Robin.
"Then you can't call him Winnie?"
"I don't."
"But you said -"
"He's Winnie-ther-Pooh. Don't you know what 'ther' means?"
"Ah, yes, now I do," I said quickly; and I hope you do too, because it is all the explanation you are going to get.
