Answer:
What kind of cheese is made backwards?
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 can fill a room but takes up no space?
Golden treasure I contain guarded by hundreds and thousands. Stored in a labyrinth where no man walks Yet men come often to seize my gold. By smoke I am overcome and robbed then left to build my treasure anew.
What is always coming but never arrives?
No matter how little or how much you use me, you change me every month.
