One day I took a bus with my girlfriend. It was so _6_ that we stood for several stops until a vacant seat was _7_ 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 _8_ her. Clearly she had taken me for somebody else. I returned her greeting with politeness，_9_ to give explanation to my girlfriend later.
Noticing my dialogue with somebody else，my girlfriend raised her eyes and found she was pretty. She asked jealously，“who’s she？” The pretty girl，quite _10_ of the situation，spoke out first，“Hi，let me _11_ myself. I’m Nancy，used to be _12_.Very glad to meet you.” She behaved very _13_.
But I was at a loss to search in my memory for someone called Nancy among my neighbors. I was worrying how to explain this to my girlfriend _14_ the pretty girl again turned to me，“Will you give me your cellphone number so that we can keep contact(联系) later？” I had to submit to her _15_.
Then the girl got off the bus at the next stop. A minute later I got a short _16_ on my phone from a stranger. My girlfriend _17_ my phone and read the note. It was from the girl，who said，“Just now，two thieves tried to pick your pocket. I had to act as an acquaintance to draw your attention. I should have left at the _18_ stop but gave up as I noticed these two thieves also _19_ to leave at the same stop. Because of the _20_ I delayed my departure. Now you’ll understand all I have done to you. Wish you luck.”
