Answer:
What is seen in the middle of March and April that cannot be seen at the beginning or end of either month?
Iron roof, glass walls, I burn and burn but never fall. What am I?
Though it be cold, I wear no clothes. The frost and snow I never fear. I value neither shoes nor hose and yet I wander far and near. What am I?
I turn everything around but I cannot move. When you see me you see you!
I am always around you but often forgotten. I am pure and clean most time but occasionally rotten.
It has no top or bottom, but it can hold flesh, bones, and blood all at the same time.
