Answer:
I am the beginning of eternity the end of time and space the beginning of every end the end of every place.
I mirror your actions.
I have an eye but am blind, a sea, but no water; a bee, but no honey; tea but no coffee; and a why, but no answer. What am I?
I am the reaction after enjoying soda.
To cross the water I'm the way. For water I'm above I touch it not and truth to say I neither swim nor move.
No matter how little or how much you use me, you change me every month.
