Answer:
I am lighter than the material I am made of. You see parts of me but more of me is hidden underneath.
*forward* *backwards*is what I do all day. I come in all different shapes and sizes. I can be scary and I can calm you down.
I can bring tears to your eyes; resurrect the dead, make you smile, and reverse time. I form in an instant, but I last a life time. What am I?
I cannot be bought cannot be sold even if Iām sometimes made of gold.
I turn everything around but I cannot move. When you see me you see you!
No matter how little or how much you use me, you change me every month.
