How does one know if he/she is considered to be a close friend of an INTP? How does one know if he/she is in the INTP's inner circle? What do INTPs do/say for/to their close friends that they wouldn't do/say for acquaintances?
I am an ENFP and I find it rather easy to befriend all types-- although obviously there are always exceptions. At times, I may take for granted my ability to really get to know someone well (ie. a friend sharing intimate details) and it doesn't always register at the time what a big deal it was for them to do so. I don't want to make the mistake of doing this again.
Oh! I also have a few other questions:
What traits do INTPs look for close friends?
Which traits can INTPs NOT STAND in people?
What are the traits specifically in ENFPs that INTPs admire/relate/ are attracted to?
What are the traits specifically in ENFPs that INTPs are annoyed by or dislike?
