Fantasy Friday: Floating (Short Story)

I don't get it.
I can see them.
All of them.
Other balls of floating light.
Other little dots in the sky.

Are there others?
Others like me?
Trapped and encompassed in this ball of light
Forever floating.
Forever trapped.

I look at the sky and I know it must be infinite.
But it looks so finite.
No matter how many balls of light there are.
There are only so many I can see.
So to me, that's all there is.

When another ball of light passes mine.
I wave. 
I wave so hard.
Hoping there's someone there.
Hoping someone else can see me.

But so what if they do?
I'm trapped in my ball.
They're checked in theirs.

Nothing can free us.
Nothing can join us.
If anyone else even exists.
