P2 Riddle

One sheet, two-sheet, three sheets or four…some use less and some use more. What am I?
What has arms and legs, but no head?
What can’t be burned in a fire nor drowned in water?
I have a big mouth and I’m quite a load. I’m not gossip, but I get involved in everyone’s dirty business. What am I?
Stepping out? Wear me first! I’ll protect your feet from the worst.
Tall and strong, I stay outside. The sun, the rain, they’re by my side. I give birds homes and help you breathe. I even give you fruit to eat.
Here I come and there I go. I move really fast, anywhere I go. That’s why you take me when you’re in a hurry. When I zoom by, I might look blurry.
You say we’re pals, that we’re best friends. But only until the morning ends. You say I give you fuel for the day. And when we’re done, you’re gone away. 
 Don’t frown at me, I made it clear. Won’t make a difference if you’re near. Just stand in front and I’ll show you exactly how the world will know you.
