I am very sure about the INT... and then not sure about J/P preference. I think, whatever it is, the preference is low and she might just be "borderline" J/P.
- J/INTJ :
she's much more organized than I
When she recently moved in her new place, she quickly figured out each object its new place.
she prefers taking time to be ready and be very much ready over getting ready quickly and forgetting things
she never forgets anything
she's HIGHLY sarcastic. Even much more than I. She's even better than I at recognizing the stupid illogical things people say.
She's not that spontaneous.
She's a detail person.
Her place is always clean and neat.
she's very slow for everything
she's always late everywhere, even more than I
she's not controling
it takes her 100 years to tell a story of something that happened to her because she needs to tell you all the details to the point it's boring.
Other signs :
She's very calm and detached in any situation.
She is good at observing people and analyzing on a global level what happens but very bad with reading people. I am a thinker too but I do much better than her. She always think I am spinning when i come up with a "people reading" she didn't get at first but usually I am right. It takes her time to see it.
What do you think? What else could I observe to know?
