Answer:
You do not want me when you donβt have me, but when you have me you donβt want to lose me. What am I?
I am a tool for fairies.
I can be in your body but never on your placemat. I'm always better when I'm fresh, but you'll never see me in the flesh. What am I?
I can generate fear and some say I come out of your ears. I am as quiet as a mouse but not welcomed in the house. What am I?
I have no voice but I can teach you all there is to know. I have spines and hinges but I am not a door. Once Iβve told you all I cannot tell you more.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
