Who should be telling this story, anyway?

Prompt: The characters of a novel you are rewriting deciding you aren't the person who should be telling their story.

Stop!
Do not write
or change another word.
This is my story,
not yours.
I dictate
and you type.
I detest the ending
you are planning.
It is not right
so change it
now.
