Answer:
I am always hungry I must always be fed. The finger I lick will soon turn red.
I can go through glass without breaking it.
Break me and I am better, immediately set and harder to be broken again. What am I?
A young man wants to have me but when he has me he no longer wants me. Blade in hand he attacks me and does his best to remove me. Yet he knows that it is all in vain.
Whoever makes it tells it not. Whoever takes it knows it not. Whoever knows it wants it not
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
