Shadows

I am but a shadow in their world
important enough to keep their status normal.
When present, they give me faint notice.
Without, there is an air of eerie.

I am but a shadow in this world.
My existence is fleeting as the sun sets.
He greets the rising moon,
as I fade into the perilous dark.

I have shadows in my world.
My heart, my mind, my soul --
all shrouded in the silky, silent blackness.
It's thickness stifles my voice.

I am a shadow.
It's the core of my being,
fleeting from light, seeking solitude.
Pondering my very existence -- I know I must exist for them:
To keep their lives stable.

And yet where is stability in mine?
It exists only in the rare moments that I,
as a shadow, match the movements of you;
you, the world;
I exist, as a shadow;
as a being, to serve you.
