Bob is a 60-year-old man. He likes Beijing Opera very much. He usually watches it on CDs.
Today, he goes to watch Beijing Opera in a theatre(戏院). It is his first time to watch Beijing Opera there. He buys a ticket from a theatre worker and goes into the theatre. But after a minute, he comes back to buy a second one. And then a third one.
The worker is very surprised. She asks Bob, "Only you come to watch Beijing Opera. Why do you buy so many tickets? "
"Oh, the boy at the door to the theatre always tears(撕毁) my tickets. "
