So try it. Write from the perspective of someone else, imagined or real, that you would not normally consider, because they do not personally touch your life. Give thought to their situation, their physical reality (cloths, face, eyes, hands, the places they dwell in, etc.), and their emotional and mental state at the time of the writing. See through their eyes and write from their perspective.
Its amazing how eye opening this exercise can be.
Here is an example:
It is dark beneath the shadow moon,
as she walks the streets,
alone in her plight.
She is no more than a wisp of smoke
to those who pass her by,
unnoticed and uncared for,
she is forgotten.
Her face is covered in filth and dirt,
caked layer upon layer,
and her eyes are glazed and empty as
her silent pleas for help go unheard.
A single tear smears the dirt as
it traces a path down her cheek
and falls onto the tattered rags
she wears to survive the elements.
She stares through windows
into a world of sheltered security
that she will never have,
that she will never be a part of,
and she can do nothing more
than stand in her confusion,
lost in the world of the past
when she walked among the living of society.
But always reality is brought back to hern
for she is shunned for being unable
to live up to the expectations of society
and she is disregarded as nothing more
than a burden upon society.
And she wonders where
she will sleep tonight,
and if she will live to see another day
of hunger and loneliness.
Yesterday she was a
wife and mother,
with a family,
and a job,
but today, well, today
she is a forgotten nothing,
a shadow of society.
