Answer the following question: Read the article and select the best answer. Article: The English are often described as unfriendly people who don't talk to strangers . But not London taxi drivers. I once asked one cabby 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 strange things happen late at night. The other day I was taking a woman home from a party. She had her 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 her dog while she climbed in through 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 in through the window. The next thing I knew was that the police came. They thought I was 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." Question: Why do you think the woman didn't go out of the house again. Options: A: Because she didn't want to pay the taxi driver. B: Because she was so tired that she had forgotten about the taxi driver. C: Because she wanted to keep the taxi driver waiting. D: Because she wanted to go to sleep first.
