I just found out that I am! My dad's an ISTJ, mom's an ESFJ, and my sister's an ESTJ. I can't say that I've ever really gotten along with them.
They all seem to believe that authority and deferring to it is some rationale. It's kind of stupid when all of your arguments end with, "I own this house and if you don't like it you can move out!" The more you reason the louder they yell that same line. It's like talking to a wall.
I used to get really upset over this but now I just shut up and don't give a crap. The fact that they're SJ's just helps me to not give a crap even more. If they don't get me now they never will.
Other stuff that annoys me is my moms ability to come up with a seamingly endless number of things that have to be done and when we haven't done all of them or haven't done them in just the right way she expects us to, she turns the biggest whiner. Grow a backbone woman!
I could go on and on about the various ways that we're different but I won't. Needless to say, it's tough. As an NF I really need someone who will believe in me and stand by me as I venture into adulthood and find a career for myself and my family's been more of a hindrance than a help. They just don't get that I'm never going to come around to value the sames things as them and that by telling me my values are stupid they're just delaying my departure.
Ughh... combine that with my addiction to MBTI and MP3 player forums and at the end of the day I can't help to feel as though each day has been any different from the last. Any NF's here have any killer careers that they really enjoy?
