The Moon, The Heart

So like a moon can be the human heart:
Both being half in darkness, half in light;
A heart hides secrets, lest it break apart,
Then bares them to the benison of night.
Not brave enough to face the eye of day,
A heart needs solitude in which to weep,
Letting the tide of sorrow have its way
While all the world has lost itself in sleep.
A heart must find a shadowed place to cry,
Remembering the beauty that has been;
And, though the moon's bright face may gild the sky,
Its side of darkness, mortals have not seen.
A heart will show its joy to the sun
But turn its breakage to oblivion...
