A: That’s good, I am very happy that you know that. I hope more and more people can know that. And if we all know that, much fewer people will die in the accidents. There must be fewer and fewer accidents, too!

 B: That’s aright. Let’s tell others about these and then, as you say, our world will be more beautiful.

 A: OK! Let’s go!

 B: Oh, wait a moment, I want to see that bus driver again.

A: That bus driver? Why?

B: I know how to say to that rude bus driver.

 A: What?

 B: I will tell him: “Your bus can carry a bike, but my bike cannot carry a bus! Be careful, Sir!”
