Answer:
I am there when you sit, but gone when you stand. What am I?
I mirror your actions.
I am the beginning of eternity the end of time and space the beginning of every end the end of every place.
No matter how little or how much you use me, you change me every month.
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?
