E) I am

I am the dead sound
you get from something that's been hit
once too often.
I am the one who's eyes
you won't meet in the street.
I am the dusty piece of jigsaw
at the bottom of a toy chest:
no one knows
what picture I belong in.
I am out in the moonlight
when you've drawn the curtains.
I am not like you
and you'd leave me behind
if you could.
