The sky

If you go outside and look above you,
You will see a completely different world.
Maybe you'll see some fluffy clouds,
Or a tiny little bird.
The sky itself might be blue,
Or black, or something in between.
What you definitely won't see,
Is a sky that is green.
You might see plane,
Carrying people you do or don't know,
Leaving a lovely trail,
Of what seems to be snow.
If the sky is dark enough,
You might see some stars,
And wonder if you can reach them,
(You can't they're very far).
You might a large white sphere,
A round and perfect moon.
Or it might not be quite so round,
Like the end of a dessert spoon.
If it's day time you will see,
A large and bright sun.
If it's surrounded by lots of red,
The day or night has just begone.
