Answer:
I run through hills. I veer around mountains. I leap over rivers. And crawl through the forests. Step out your door to find me.
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 am rarely touched but often held and if you are smart you'll use me well.
Everyone asks for me but yet everyone hates to face me. For someone I am agony, for others I am relief! What am I?
I move without wings, between silken strings. I leave as you find my substance behind. What am I?
A little house full of meat, no door to go in and eat.
