     In this age of Internet chat, videogames and reality television, there is no shortage of mindless activities

to keep a child occupied. Yet, despite the competition, my 8-year-old daughter Rebecca wants to spend her

leisure time writing short stories. She wants to enter one of her stories into a writing contest, a competition

she won last year. 

     As a writer I know about winning contests, and about losing them. I know what it is like to work hard

on a story only to receive a rejection slip from the publisher. I also know the pressure of trying to live up to

a reputation created by previous victories. What if she doesn't win the contest again? That's the strange thing

about being a parent. So many of our own past scars and dashed hopes can surface.

     A revelation (启示) came last week when I asked her, "Don't you want to win again?" "No," she replied,

"I just want to tell the story of an angel going to first grade."

     I had just spent weeks correcting her stories as she spontaneously (自发地) told them. Telling myself that

I was merely an experienced writer guiding the young writer across the hall, I offered suggestions for

characters, conflicts and endings for her tales. The story about a fearful angel starting first grade was quickly

"guided" by me into the tale of a little girl with a wild imagination taking her first music lesson. I had turned her

contest into my contest without even realizing it.

     Staying back and giving kids space to grow is not as easy as it looks. Because I know very little about farm

animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting (借用) my

daughter's experience.

     While stepping back was difficult for me, it was certainly a good first step that I will quickly follow with

more steps, putting myself far enough a way to give her room but close enough to help if asked. All the while

I will be reminding myself that children need room to experiment, grow and find their own voices.
