Alone moon

When I see together sun and moon,
I hope that we will be also together soon,
When i see moon between stars,
I thought you and me are ours,
Just moon can't emit its own light,
I remember that when I feel low,
You hug me tight.
When I see sun is always behind,
The moon to give a shine in the sky,
I remember your goodbye,
It's contradictory,
But truly that time I lost my glory.
Now I want to shine without sun,
I know in Science it's impossible ...
