Window Lock Down

I wrote this poem in seventh grade:

From many years of being shut,
this window is scared to open.
It doesn't trust the outside,
it's scared of what might happen.
So it just sat. And watched.

One blazing hot day,
someone opened that window.
The window saw what really happens:
beautiful birds make nests on its seal;
dirt and leaves blow through the air.
One day some children were playing,
their ball soars across the sky,
and hits the window's surface
leaving a heartbreaking crack.

That night, the window was shut,
and it decided being shut was best.
Everyone said that an open window was better;
but it stayed closed; day and night.
Where it thought it was safe.
Where it thought it wouldn't get hurt.
