Answer:
When I live I cry, If you don't kill me I'll die.
My sides are firmly laced about, Yet nothing is withinΝΎ You'll think my head is strange indeed, Being nothing else but skin.
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.
They try to beat me, they try in vain. And when I win, I end the pain.
I walked and walked and at last I got it. I didn't want it. So I stopped and looked for it. When I found it, I threw it away.
I am your mother's brother's only brother in law. Who am I?
