I wish to educate and warn you the reader of some of the more common signs that the person in question -- usually a male -- is someone you should detach from...and quickly! The sooner you can detect a troublesome person, the better off you will be. One quick check is your placement of him/r on the asshole scale. Now remember, not every jerk or idiot is necessarily psychotic! However, the psychopath is an extreme form of the "asshole" personality type, they've just learned to conceal it most of the time and appear to be "nice, charming" people. They are developmentally stuck in their early years, still fighting the battles of authority and parental control over them!
