Who am I?

I am the cry of every child
the smile of every face
the dance of every street
the tortured human race.
I am the twinkle in every eye
the shout of unheard age
the kiss on every cheek
the punch in every face.
I am the clap of praise rewarded
the clack of every cell
the shout of great victory
the pride which from you fell.
I am in all things glorious
in the act of great disgrace
in the beauty of great sacrifice
in the burden of great pain
I am in every laugh,
every cry,
every voice,
every sigh.
I am in every breath you take,
I may be real,
may be fake.
Who am I?
I am you.
