阅读下列短文,从每题所给的A.B.C.D四个选项中,选出最佳答案。

The English are often considered as unfriendly people who don't talk to strangers, but not London taxi drivers. I once asked a cabbie to describe his life to me and he didn't stop talking until I arrived home half an hour later. He told me many interesting stories and this is one of them: “Some very strange things happen late at night. The other day I was taking a woman home from a party. She had a little dog with her. When we got to her house she found that she'd lost her key. So, I waited in the cab with the dog while she climbed up the window.” “I waited … and waited … After half an hour of ringing the bell I decided to find out what was going on. I tied the dog to a tree and started to climb up the window. The next thing I knew was that the police came. They thought that I was trying to rob the house! Luckily, the woman came downstairs, she'd gone to sleep and forgotten about me and the dog. I was in such a hurry to get away that I forgot to ask her for the fare(车资,车费).”
