I never speak, yet set the mood, I dress a room in attitude. Not walls or floors, but still I’m seen - What am I that makes spaces feel mean in a good way?

If you want my return then toss me aside but with greater care I'll bag you a hare.

I can store data but have no brain, I float in the sky but feel no pain, Who am I ?

I have fingers, but cannot hold. I brave the chill, yet feel no cold. I come in pairs, a matching sight, shielding touch from winter's bite. What am I?

I am a bridge that crosses no water, and abed that touches no floor. I have a back but no spine, and though I am always hanging, I have committed no crime.
