Answer:
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 am needed for most animals and hardcover books
You get embarrassed when you stand on me when everybody is watching. Women don't like to talk about the number they see on me. Everyone stands on me when nobody is around
I am gentle enough to soothe your skin light enough to fly in the sky and strong enough to crack rocks.
I am born in fear raised in truth and I come to my own in deed. When comes a time that I'm called forth I come to serve the cause of need.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
