One Shadow of Many

You've got one second.
One Minute.
One Hour.
One Day.
One Year.
A Lifetime and a half
Just to see the silhouette standing before us
That shows nothing about ourselves
Yet tells our whole life story.
You can't see yourself,
Yet you can recognize who you are
Out of the sea of shadows
Mimicking our every move,
Our every stride,
And our every breath.

My first poem. Hope you like it.

Not sure if it'll make much sense to others, but lets hope it does!
