All the while

All the while, 
walls behind ,walls beside.

One path, straight forward, walk the line.

Couldn’t see 
you can climb, 
now your free.
Stretch your wings 
start to fly.
Threw the glass,
and beyond the grasp,
Trees and grass,
is all to cast,
Nature’s past,
 to present path.

All the while, walls behind,walls beside.
There was a door. 
you  just couldn’t find.
