The other day I made a post about someone who was breaking my heart. After comparing notes with other people who know them, we have discovered that this person is a game playing narcissist.
While a member of the non-profit I used to run, this individual would go to Person A and say that Person B had acted in a sexually inappropriate way towards them. They would then go to Person C and make that same claim against Person A.
I wrote this individual a letter of recommendation when they were applying to colleges. Fortunately I have discovered a process where I can get their current University to pull that letter from their file.
I guess it's true that Sociopaths can be charming people.
Sociopaths do not use charm to manipulate...you are thinking of a Psychopath.
I think "shitbag" would work just as well.
