I am a carousel.

I am spun around in a circle of flying colors,

Not a care in the world.

And then I am sat on,

And the flying colors fade into darkness,

And the small circle becomes the solar system.

I am Pluto.

Forgotten and dark, barren.

I spend 248 years in one orbit around the giant mass people call the Sun.

Or maybe I am Planet X.

I am a carousel.

People pay for me to cheer them up, 

But whenever I need it,

All of the customers disappear.

They decide they have better things than me.

I am a carousel.

I am made of many parts.

And when one of those parts breaks,

I am

Broken.
