Children

Directly opposite my window there is a school. For some reason it got me thinking...

Children,
I see you sitting
Near the ceiling,
Below me, but
I remember being you.
Staring out, I saw
A river of glitter
Running through a field,
Or thought I did,
But was it real?
Have you seen
What you may not believe?
I hope it never
Happens to any of you.
If I were you
I'd be so far away,
Inventing a game.
Sometimes
I miss those days.
