     When I was 19, I had got a job in my local bookstore. Living in the large city, I usually saw many strange

customers(顾客), most of   1   were teenagers. They didn't come often; I forgot all the customers   2   two.

One night a 15-year-old girl came in looking for a book with a boy. They seemed to find what they wanted to

buy. But   3   they came to the counter (柜台),the girl found she was a dollar or two short to buy the book,

and she took   4   all her money to prove it. She looked so disappointed. Just then I remembered my discount

card and   5   was still active, so I told the girl   6   to worry. I put in my code (密码), being happy that I

could help them with this card. With the book in her hand she gave me   7   thankful smile, and then she and

the boy got out of the store happily, leaving me feeling content, too.   8   fact sometimes a little thing can also

make one's world beautiful.
