Answer:
When set loose I fly away. Never so cursed as when I go astray.
The warmer I am the fresher I am.
Die without me, never thank me. Walk right through me, never feel me. Always watching, never speaking. Always lurking, never seen. What am I?
I have a little house in which I live all alone. My house has no doors or windows and if I want to go out I must break through the wall.
I am commonly ate before I'm born and after I'm dead.
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
