B: You think I am stupid? Of course I know, and I also know, you will say: “these moving buses are all dangerous…”, right?

 B: I know! I know this and that. I know to be careful, and I also know the traffic rules, just like I know how many fingers I have.

 B: Wait…

 A: He is helpful. He always helps lost children…liuxuepaper.com
