- Oh, my. Someone broke their promise. Hmm. I'm quite certain it wasn't me.
- It must be from my best friend Piglet.
- He really shouldn't have. But I'm glad he did.
- I must give him something as wonderful in return. Perhaps a jar of honey.
- But I'd better not tell anyone, including me. I've never been known for keeping a secret.
- Yes?
- Piglet, you promised not to do it.
- I'm sorry, Pooh. I promise not to do it again. What did I do?
- You gave me a wonderful jar of honey as a valentine gift.
- I did?
- And if you ever do such a thing again, I shall have no choice but to thank you again.
- Happy Valentine's Day, Piglet.
