Answer:
I am free the first time and the second time, but the third time is going to cost you money. What am I?
I can fly but I have no wings. I can cry but I have no eyes. Wherever I go darkness follows me.
I am the noblest musical instrument
I spend the day at the window go to the table for meals and hide at night.
I hold two meanings. With one I may be broken with the other I hold on.
No matter how little or how much you use me, you change me every month.
