After a few minutes he comes out again and buys a third ticket. Two or three minutes after that he comes out the fourth time and asks for another ticket. The girl says to him, “Why are you buying all these? Are you meeting friends in the cinema all the time?”

     “No, I'm not doing that,” the boy says. “But a big woman always stops me at the door and tears(撕掉) my tickets.”
