Shattered Glass

I wrote this poem myself... it is a metephor it should be pretty easy to get

Tossing the rocks
Towards a red tinted glow
One went right through
That beating window

A force that smashed
A crash that hurt
And there lie the pieces
Broken in dirt

Hopes had been broken
A safe haven trashed
Comfort comes slim
When dreams have been crashed

My shaking hands reach
To touch what remains
A once beautiful combination
Now just cracked window panes

I careful pick up
The remnants of class
To cherish forever
My now shattered glass
