Answer:
I fly forever Rest never.
I am quick when I'm thin. I am slow when I'm fat. Wind is my worst nightmare. What am I?
I can be hairy and itchy all over. I can be the scariest thing you have ever seen. I stand in the middle of nowhere, hanging on a stick. What am I?
I am the beginning of the end and the end of time and space. I am essential to creation and I surround every place.
If you're looking for something sweet I know what to do. But if you don't like heat I'm not for you.
The more of me you take, the more I appear behind you. What am I?
