"A Monster Inside"

He looked in the mirror and he could not hide
The horrible monster that was inside
He tried to run and he tried to hide
But the monster always matched his stride
It ran with him and kept his pace
And always showed upon his face
The monster inside was always there
Never absent
Always there.
Whether it was in his mind
Or it was really there
The monster inside was there all day
And very soon it would catch its prey.
