You
- were the pen I wouldn't use in writing
the paper I wouldn't crumple or throw for shredding
the music I wouldn't let them hearing                                                                                                                                                                            
and the book which pages I'd continue turning.  

You
- were worth keeping and remembering
I
- was the game you keep on losing
the battle you wouldn't be fighting

I -
  was the letter you keep on forgetting.
