question: can you guess what i am.  you always hold me but you cant see me.  unly way you can see me is if im looking at me.  you use me everyday withought knowing.  i hurt with bright lights whcih makes me get bigger.  i make water out of thin air but you rub it then its no longer there.  when you use me you give me a "stare" but when you dont use me.  you dont know im there.
