Night that fight the light

As the moonlight shines through windows,
Fighting with dark on the wall
Casting shadows as it battles
Defeated as the darkness takes it all
But bouncing back for round two,
Ready again to start the fight,
Dancing shadows all around them
The light has won over the night.
This game is forever,
Tell it to us all
For when dark has punched the lights out,
Dark begins to fall.
