Why the sky is blue?

Sometimes I use to imagine the rainbow,
And sometimes I imagine the rain.
But always, when I see my view, you are always there.

Sometimes I'm trying understand your reasons.
You always there and you are always blue.
And every time you cry or smiling, like today,
I just stare.

Why?
Why is the sky so blue?
Why?
I know it's true, but still I don't see why?
Why there are no stars there,
in the morning time.
Why is the sky there?

Sometimes, when I awake at the early morning,
The sky have dressed in its black dress.
And the stars are decorate,
its unique dress,
And I just stare.

So why?
Why is the sky are black?
Why?
Why is every star shines in white.
I don't want to hear another story,
and why the sky is blue or black?
Tonight.
Why won't you tell me?
I asked it at least ten times but there's no answer.
The sky is blue but it have its reason.
I keep on wondering why?
Why the skies are shine in blue?
Or maybe they don't.
So why won't you say?
