Psychopaths
spend their time studying everyone else's cues and responses. We are excellent at spotting when someone is lying to us. Not to mention that we are naturally assuming every person we meet is after something.
We are always suspicious of your motives. Trying to trick one of us will likely put you into line for them to use all of your moves against you. You have no idea who you are dealing with and it would be easy for you to think you have gotten over on a psychopath, when in reality you are walking into a nasty trap.
Chances are, unless you have really done something to attract the psychopaths attention, that they will walk away and never think of you again......unless you give them reason to.
Ego is a dangerous assumption to pursue with a psychopath and we see it coming from far off
