Quote context

[...]

- Mr. Trundle's clock in the village hall. I wanted to see how it worked, so I climbed up into it and...

- Kerplunk?

- Kerplooey.

- You broke the clock?

- I didn't mean it, Father. I'm sorry. So sorry.

- It's not enough to be sorry. When you've done something wrong, you have to correct the thing you did.

- That's it. I'll fix it, Father. I'll fix the clock by midnight. Then maybe Santa will...

- You believe in Santa?

- I don't know. I don't know. But I've learned that I still got a lot to learn.

- But, son, you don't know how to fix a clock.

- That's all right, Father. Copernicus knew.

- You hope, and I'll hurry. You pray, and I'll plan. We'll do what's necessary, 'cause even a miracle needs a hand.

- Good luck!

- Father Mouse?

- Merry Christmas, Mr. Trundle.

- Not very merry, I'm afraid.

- You're right, of course. And it's my fault, my family's.

- How so?
