Luna

I feel like the moon.
I fade in and out.
You can only see one of my sides,
unless you come to me.
I've been hit by others  like me
that have left some big craters.
But I still try to reflect the light I've been given.

I'm big and out there.
Sometimes I let storms hide me,
But I always come back out eventually. 
I'm hard to reach.
Harder to approach.
I'm plain yet confusing.
My rules don't always make sense.
But I am what I am.
I am like the moon.
