Sherlock Holmes (Book and BBC): For their specific filtering and storing of information.
Dr Hannibal Lecter (NBC): We are much alike and I adore the way his moral works. 
A psychiatrist I once met: The way we were equal on playing the games, and working our way around, without getting anyone else noticing. We got equal insight in each others minds for a glimpse.
A certain empath: For showing me a view on the world that only a corrupted mind could follow.
An experimental friend: For being a blank canvas.
