Answer:
By the way, what never moves, wears shoes, sandals and boots, but has no feet?
I open wide and tight I shut, Sharp am I and paper-cut fingers too, so do take care, I'm good and bad, so best beware.
I have legs but never walk, I may have flowers but no soil, I hold food but never eat.
Tall in the morning, short at noon, gone at night. But I'll be back soon.
I never was, am always to be. No one ever saw me, nor ever will. And yet I am the confidence of all, To live and breath on this terrestrial ball.
What covers its face with its hands, speaks no language, yet most known what it's saying?
