完形填空

Three years ago, I had a job in a retail store (零售店). I    21   to talk to everybody and know what was going on in their    22  . I remember a girl who started    23   there a few months after me. We seldom talked but we always    24   each other and smiled.
She always smiled in a really happy way    25   one day when we got to work in the    26   department. She smiled as if she was the    27   girl in the world. I went up to her and asked, “What’s wrong with you?” She answered, “Why?” I said, “I could feel you’re very    28  , but you’re always trying to    29   it.”
Her mouth just dropped as if I had    30   her deepest secret, so we started talking. She told me    31   she was feeling unhappy and why she was trying to    32   that nothing was wrong. Time went by and we became good friends. She’d always tell me I had   33   her life in so many ways.
Today that girl is one of my best   34  . I really don’t know what I would do    35   her. She has been there for me in every    36   way a friend could be.
What I’m trying to say is that you never know    37   you’re helping yourself. I helped this girl never knowing that at the same time I was helping myself by finding a    38   friend.
So the next time you see a    39   and he needs someone who will    40   to him, wait and let him say what he wants to say. You never know, you might just end up helping yourself.
