My best friend is a book,and it is called as a diary by me.It is very

  quiet.I often talk to it,but it just listens,and it never replies to me. In the

  begining,I didn't like it at all.Because it was my homework.But now,I find that

  it is interesting to talk to it.And I can also improve my writing skill when I

  talk to it.It is good at listening to my heart and I can share my happy and sad

  with it.It makes me feel relax,so I regard it as my best friend.
