INFJs are sweet and harmonious creatures that are self-sacrificing to maintain peace....they can also be huge guilt manipulators.... >.> An INFJ in any situation can do wonders for maintaining peace for a length of time.
But let's get down to functions, my friend. I'll go with the major functions so you can see where most of the conflicts come from.
ENFP: Ne Fi Te Si - Leading wth extroverted intuition, you are all about possibilities and making connections. The world is a huge ocean and Ne is your net, gathering up everything you possibly can. Following that is introverted feeling, which is about your own personal values and maintaining inner harmony. You value experience....then filter it through your value system, making certain that you are being true to yourself with everything you do.
ISTJ: Si Te Fi Ne - Leading with introverted sensing and extroverted thinking, your father's view of the world is completely opposite of yours. Your strongest functions are his weakest and vice versa. Introverted sensors take concrete information and internalize it, making a kind of schematic in their minds. Everything is broken down to a very symbolic form, the way different colored lines on a map represent different types of roads. Te is a bit controlling... It attempts to organize the outside world. With sensors especially, this means that fact is fact....and possibilities are not as substantial.
As a side note, my INTJ friend has an ENFP brother and an ISTJ father.... ISTJs tend to be more appreciative of ENFPs who they aren't related to, and for some reason simply cannot perceive the same positive qualities in their own children. They see a stubborn day-dreamer who only lives to defy them I think.
INFJ: Ni Fe Ti Se - Introverted Intuition is an internalized connecting of information, which is more bent toward making hypotheses and planning than Ne is, and extroverted feeling is more about external harmony and the good of the whole rather than the happiness of the individual. Fe has difficulty discerning personal problems from those of family and friends....and wants to solve everyone's problems. INFJs are simultaneously frustrated and loving of their families....they want people to make sense the same way INTJs do, but on a more emotional, connected level.
NFs tend to get along pretty well....though we all have the famous explosive NF emotional explosions. >.> The biggest frustration for an INFJ with an ENFP is our seeming listlessness....an INFJ is very good at knowing what they want and making plans to get it. ENFPs....well, we seem pretty lazy. And one of the funniest reactions I ever got from my INFJ friend was when I told her I have to know I can just get up and leave at any given point. No destination. No plan. Just go. She looked absolutely horrified.
ESTJ: Te Si Ne Fi - Same functions as an ISTJ, just flipped....putting organization in the lead and following it up with symbolic concrete information. As a result, ESTJs are more vocal about what "doesn't belong" or rather what is out of place to their organized view of the world.
My mother is an ESTJ....so I'm having trouble perceiving her in any other light than as a parent. They're kind of a mix of indulgent affection and stern expectation. Like....they'll always be there for you and help you out if you need it...but they have no problem telling you that you were an idiot.
