120 It’s Too Late
A mother and her child are walking along the street.
（C=child； M=mother； W=waiter in a restaurant）
C： Mom， I need to go to the washroom.
M： Uh-oh！ Can’t you wait？
C： I can’t stand it anymore.
M： OK， let’s go into this restaurant. Excuse me， but can my son use your toilet？
W： Of course not. This is a restaurant， not a public toilet.
M： You’re so mean.
W： Oh， OK. But it’ll cost you US$5.
M： What？ That’s highway robbery.
C： Mom， never mind. It’s too late.
W： Hey， come back here and mop the floor.
