Who was me? Who am I?

All my life a question took hold of my mind Who was me? Who am I? Was I my parents adored young child? Or am I the bird that gazes at the sky? I looked for a moment to fly Perhaps I am someone else, perhaps I changed Who was me? Who am I? No matter what I never got deranged Am I who I think I am? Or what other people think of me? All my life I stood behind the dam Who was me? Who am I? Who was me? Who am I? Am I the moon round and bright? Lustrous and whole a marvellous sight? What will I be the day I die!
