Answer:
What flies without wings?
When you take away the whole from me there is always some left.
They come out at night without being called. They are lost in the day without being stolen. What are they?
I am quick when I'm thin. I am slow when I'm fat. Wind is my worst nightmare. What am I?
I am there when you sit, but gone when you stand. What am I?
Before I grow I'm small. When I'm old I grow tall. When I die I give a mighty fall.
