Answer:
Use me if you really want to see inside someone
Every dawn begins with me. At dusk I'll be the first you see and daybreak couldn't come without. What midday centers all about. Daises grow from me I'm told. And when I come I end all code but in the sun I won't be found. Yet still each day I'll be around.
What has a face and two hands but no arms or legs?
I am asleep when you are awake I am awake when you fall asleep. I can fly but no feathers to aid my flight.
I go in hard come out soft. Blow me hard and I’ll make a pop.
No matter how little or how much you use me, you change me every month.
