I Wonder

I wonder why is grass is green,
And why the wind is never seen?
Who tough the birds to build a nest,
And told the tress to take a rest?
Or,when the moon is not quite round?
Where can the missing bit be found?
Who lights the stars,
When they blow out,
And makes the lightining fash about?
Who paints the rainbow in the sky,
And hands the fluffy cloud so high,
Why is it now, do you suppose?
That Dad won't tell me,if he knows.
