I'M Not a Clock Or Bird Or Tree

If I was a clock, I'd tick all day long. I'd march like a soldier, To a marchy march song. Or maybe I'd be a bird, And fly through the sky. I'd fly up through the clouds, Just to keep myself dry. Or better still I could be a tree, And be five hundred years old. Standing still through the winds, Heat waves and the cold. But, alas, I'll never be a clock, Or a bird or a tree. I'm resigned to the fact, I'll only ever be me.
