I have four legs and eat grass I am noisy when I am angry and stubborn otherwise I may be called stupid and unwise All of you have me

Black as night, I watch and wait Clever mind, but dark of fate I feast on secrets, scraps, and grime If too many of us gather it might be a crime

I am a creature of the night, add one letter and I cover you, remove one and I am hurt

I am a ghost that clings to stones, a whisper born from breaking bones. The sky must bleed to call me near, yet I am gone before I’m clear. I do not live, I do not die, I only breathe when earth will cry.

I sometimes disappear, though I am always around. I am a reflection of what I seem to be. I grow bigger or smaller, but stay the same size. Some say I can affect delivery.
