Congratulations! You hit the .... On it's head.

Someone left this mallet, Oh, no... That letter was upside down. Best if we return it.

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 ?
