people and Windows

People are very similar to Windows.
Some are closed, others are open.
Some have glass, others tightly shuttered.
Some are permanently broken, others reflect the bright lights.
And there are Windows to nowhere and with a view of the cemetery.
Accented with colored glass... Nice, but tiring.
And are mirrored on the Inside... you can see everything, and to look back not...
The Windows have a common property: they look at each other or ourselves.
Rare window look at the sky...
