Dialogue between Ali and Xiaoyun?

Xiao Yun: Ali, do you know why it is sunny?

Ali: Why?

Xiao Yun: Because Yun went on a trip.

Ali: Oh, they will come back and take you home.

Xiaoyun: Well ... maybe.

Xiao Yun: Ali, do you know why it rains?

Ali: Why?

Xiao Yun: That's because there is a cloud crying in the sky.

I see. I guess that cloud in the rainy season must be very, very sad.

Xiao Yun: Well, because he can't travel with everyone. Clouds are destined to travel far.

Ali: Xiao Yun, you will fly back to the sky, too. Travel around the world happily with friends every day.

Xiao Yun: Hmm!

Ali: Good night, Xiao Yun.

Xiaoyun: Good night, Ali.
