Answer:
I have cities but no houses I have mountains but no trees I have water but no fish. What am I?
Who makes it, has no need of it. Who buys it, has no use for it. Who uses it, can't see it. What is it?
I shrink smaller every time I take a bath.
I can fly but I have no wings. I can cry but I have no eyes. Wherever I go darkness follows me.
I have a strong affection for belly buttons.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
