She would open a book, pretending to read, with tears dropping on the open page. All I knew was that she was an orphan (孤儿) from Africa.

I , at that time when I was looking at her excited face, she’d probably never anything in her whole life. Everyone started to their hands. Suzy Khan gave them a shy smile and the applause was defening. I knew then Suzy was going to ne all right.
