Answer:
You can read me both ways I wear; One way it's a number reversed a snare.
What is brown and sticky?
Drop me and the world will shatter. You can always find me where you empty your bladder.
With a halo of water and a tongue of wood; stone as skin long I stood.
When you take away the whole from me there is always some left.
What begins and has no end? What is the ending of all that begins?
