- Piglet's much less lost than he used to be. In fact, I believe we've found him. Hello, Piglet.

- Hello, Pooh.

- Now, that we've found you, I'm very, very sorry for having misplaced you in the first place. Will you forgive me? I promise I shall never, ever lose you anymore.

- Piglet? Piglet! Oh, I've done it again.

- Excuse me, but you didn't lose me, Pooh. I came out here all by myself to practice my singing, after you said how it bothered everyone.

- Why, Piglet, you weren't the bother. I was. Me and my habit of losing things. Isn't that so?

- Yep, buddy bear's the one.

- Yes, thank you... I think.

- So, you see, I've learned my lesson. I'm never going to lose anything again, provided I can find it.

- Wait a minute! Enough of this lost and foundies.

- Did you say you were singing, Piglet?

- Yes.

- Ah! I never knew you could.

- Well, actually...

- Why didn't you ever tell us?

- Yeah, yeah! Go ahead and hum a few bars.

- Oh, now, I don't really sing all that wonderfully. I'm just a beginner, you know.
