I cannot be other than what I am, until the man who made me dies. Power and glory will fall to me finally. Only when he last closes his eyes.
What do you fill with empty hands?
I run through hills. I veer around mountains. I leap over rivers. And crawl through the forests. Step out your door to find me.

I have a face, yet no senses. But I don't really care, because time is of the essence.
What is always coming but never arrives?
