One day I took a bus with my girlfriend. It was so that we stood for several stops until a vacant seat was for her. Then a pretty girl rushed towards me, saying, "Hi, where are you going?" I was so struck by the stranger that I had a hard time trying to her. Clearly she had taken me somebody else. I returned her greeting with politeness, to give explanation to my girlfriend later. Noticing my dialogue with somebody else, my girlfriend her eyes and found she was pretty. She asked jealously, "Who's she?" The pretty girl, quite of the situation, spoke out first, "Hi, let me myself. I'm Nancy, used to be . Very glad to meet you." She behaved very . But I was to search in my memory for someone called Nancy among my neighbors. I was worrying how to explain this to my girlfriend the pretty girl again turned to me, "Will you give me your cell phone number so that we keep contacts later?" I had to submit to her . Then the girl got off the bus at the next stop. A minute later I got a short on my phone－from a stranger. My girlfriend my phone and read the note. It was from the girl, who said, "Just now, two thieves tried to your pocket. I had to act as an acquaintance to draw your attention. I should have left at the stop but gave up as I noticed these two thieves also to leave at the same stop. Because of the I delayed my departure. Now you' ll understand all I have done to you. Wish you luck."
