Answer:
What is often returned but is never borrowed?
Something wholly unreal, yet seems real to I. Think my friend, tell me where does it lie?
I have it, I don’t share it. If I share it, I don’t have it. What is it?
What can be forever wound up but never annoyed?
I can sizzle like bacon, I am made with an egg. I have plenty of backbone, but lack a good leg. I peel layers like onions, but still remain whole. I can be long, like a flagpole, yet fit in a hole.
If it’s information you seek, come and see me. If it’s pairs of letters you need, I have consecutively three. What am I?
