Answer:
What is it something that you always have but you always leave behind?
Three little letters. A paradox to some. The worse that it is, the better it becomes.
It is destruction made out of thin air, You hear it howl and give a prayer, Through barns and houses it will tear. It is a deadly funnel, Of violent and twisting air.
What is given but kept by the giver?
Held firmly in the hands, like a sword it cuts deep. Bloodless strokes, all, then forward we leap.
I'm the source of all emotion but I'm caged in a white prison.
