Answer:
The warmer I am the fresher I am.
What do you call a fish with no eye?
I go around and in the house but never touches the house
I am the outstretched fingers that seize and hold the wind. Wisdom flows from me in other hands. Upon me are sweet dreams dreamt my merest touch brings laughter.
I hold two people together but touch only one.
No matter how little or how much you use me, you change me every month.
