Answer:
Take it and you will lose or gain more than the others.
Lovely and round, I shine with pale light. Grown in the darkness, a lady's delight. What am I?
I shrink smaller every time I take a bath. What am I?
If you lose me, you may cause people around you to lose me too. What am I?
There's not a kingdom on the earth I haven't traveled over and over and though I know not whence my birth yet when I come you know my roar. I through the town do take my flight and through the fields and meadows green and whether it be day or night I neither am nor can be seen.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
