Just after I got on the bus, Jack came to stand very close to me. It made me very uncomfortable. He began to ta lk with me, but I didn’t like the way he spoke. Many people watched us from time to time because he talked loudly on the bus. And he dropped waste paper on the floor. He asked me many questions, and I answered his questions politely. But when he asked about my age, job and family, I felt unhappy. So I told him with a smile, “I’m sorry, Jack. It’s a secret. Would you mind not asking me such questions?” “No, not at all,” he said.
