David, let me ask you a question: What do you want to do ten years from now?

Ten years from now... I want to speak Chinese with my grandmother.

Does your grandmother live in China?

Yes, she does. She can't speak English, and my Chinese isn't very good yet.

So you're learning Chinese for her?

Yes. I want to hear her tell me stories about when my mom was little.

That's a beautiful dream. Ten years is too long. I think you can do it in two.

Really? Then, teacher, what do you want to do ten years from now?

I want to write a book to help people from other countries learn Chinese.

Then I'll buy your book! I'll be the first one!

All right, I'll give you the very first copy.

Ten years from now, let's have tea together again and talk about today, okay?

Okay, it's a promise.
