Windows

Windows are important:

They can allow light to pass through from the outer world,

or they can be covered with curtains to block it all out.

They can be completely transparent and let everything be seen and saw,

or they can be translucent and only let snippets of things be seen and saw.

Windows can be opened, allowing things in

or they can be closed to keep everything inside within its border.

They can be however big or small, wide or thin.

But the windows are depend on the owner.
