Mr Johns went into his tea shop again one morning, and sat on one of the seats at the counter (柜台). Many other people came in also, but most of them did not stay long. After fifteen minutes, a young man and a young woman came in. There were only two empty seats at the counter, one on Mr Johns' left, and the other on his right. The young man sat on one, and the young woman on the other, but Mr Johns immediately asked to change places with him so that the man and the woman could be together. “Oh, that isn't necessary (必要的).” the young woman said, but Mr Johns insisted. When the young man and the young woman were side by side, the young man said to her, “Well, this kind old man wanted us to sit together, so may I introduce myself? My name's Jack. What's yours?”
