You cannot lock them up when they are in their element. They represent true freedom. Every prisoner dreams of just flying away with such ease. Birds are free like the clouds. Over the long years of prison isolation you become addicted to looking out of your window.
Every day is a different view and a different story.
Another page in life. When it rains, you are treated to the smell of the air that brings back to your childhood. The smell is unique to fresh falling rain. A window connects the prisoner to the outside world as nothing else can. Sunshine and darkness arrive every day.
