Moonlight.

Cascading down through the ever green trees, the moon filters out all the colour. They have begun to see things that were normally invisible to the untrained eye. There is a man walking through the leaves. His silent footsteps make him untrackable. There is a woman sitting at the edge of the forrest, staring across the black ocean. The moon shone upon her face, casting an eerie glow into her eyes.
The man walking, slowly and silently, unknowingly creeping upon this distraught woman. She is unaware that soon she'll be watched, for she completes the man's loneliness without ever meaning to do so.

The hours pass by, and the moon slowly fades from view, causing both man and woman to return to their fruitless lives.
