Shadow Self

I have a shadow self that no one sees
And through it, I'm who I want to be
I leave it behind when I go,
My shadow self whom no one knows

You may have seen it on a page,
Without my churning, boiling rage,
Serene and content as shadows should be
That little nameless part of me

It lives its own life, away from my head
And stays awake while I'm in bed
I never talk with my other mind
And yet we think together all the time

My shadow rests while I am here
Ready and willing, and still so near
For if I should tire if this dreary place
I shall simply put on my other face
