Where, Who, What I Am...

Who am I when I walked the path of Where, and ended up with nothing but What?

What I was, I am no more
What I was, I wasn't
Who I am is history
Who I was, forgotten

Where I've been, my past is lost
Where I walked, now covered
Where I was is now no more
Where I was, no longer

When I was, the time has passed
When I was, I'm not
Where, Who and What I am
I'm no longer sure....
