When there is someone who has either done something to me or acted in a certain way towards me (unpleasant of course), I immediately put them on my "sh*t list" and from that moment on, I may go out of my way to make things difficult for them. Not in a way that it would be harmful, but I would not go out of my way for them. Are any other INFJs here that are the same way? Okay, at times, I may do something evil as revenge (as long as this does not go against my own values).
Are INFJs pretty black and white when it comes to liking and hating people? For myself, if somebody does not engage me, I really don't have any interest in conversing with them.
