     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 8yearold 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

coopting(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 away 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.
