My Best Friend Is Faceless

My best friend is faceless,
Though he wears many masks.
His voice is silent
Yet its volume,
Unparalleled
It echoes through
The rocks, the trees, the breeze;
Through steroes,
Cacaphony of children.
He is the sun and the shadow,
An expert at hide and seek,
Hidden yet right in front of your face.
He is never quiet
But we barely listen
Still
He is there
