Answer:
What goes up but never comes down?
I am constantly overlooked by everyone but everyone has me.
A spirited jig I dance bright, banishing all but darkest night. Air can't kill me but water can. Share me, I won't get less unless wind ruins me. What am I?
What has roots that nobody sees and is taller than trees. Up up up it goes and yet never grows?
I have more shoes than anybody but less feet than everyone. I am met in the morning but departed in the night. I may shake as if I'm angry but I won't bite.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
