Who am I?

You can't see us.
You don't know us.
But we don't know you.
We can't see you too.
We can imagine all we want.
but if you really want to know
who we used to be
and who we are now
just hit the read button.
the chapters aren't to long.
you don't even have to read it all.
because your in control.
because your reading the story of us.
