Ghost.

I shook hands with a ghost. She was pretty. Not beautiful, but pretty. She said nothing. I envied her. She gave no reply. I told her she had what I wanted. She was silent. I screamed at her to give me back my treasure. I begged her and wept at her feet to give it back, but she would not. She is a ghost. They don't say anything. They don't give anything but silence.
