In his story,
My student wrote:
“our parents decided to move to a more suttle part of the forest.”

Yes, he misspelled the word. 
And he was misusing it even if he spelled it right.

But I'm not taking points off.

Because now I want to move
To a more subtle part of the forest.
 
A place off the path,
But just off the path,
A place that everyone passes 
But not everyone sees.

A clearing bounded 
by pine needles and leaves.
Within, giving loamy earth.
The air
is the mingling scents of green. 

Sun light rays down 
Defining trees
Giving them their shadows.
Forest dust shapes the sun shafts
that shooting-star bugs plunge through.
