Answer:
The shorter I am, the bigger I am. What am I?
By Moon or by Sun I shall be found. Yet I am undone if there's no light around.
With a halo of water and a tongue of wood; stone as skin long I stood.
You can catch me but cannot throw me.
I have a name that's not mine and no one cares about me in their prime. People cry at my sight and lie by me all day and night.
Give it food and it will live, give it water and it will die.
