INTPs don't have five best friends!
I have my INTJ, and a very drifted friendship with an ENFP I've known since I was 18. I think I'm still technically the godmother of his children, but we've not even had contact in over a year (not on purpose, we're just both flakes, we both move a lot, and we haven't even lived within 500 miles of each other in like a decade).
I guess my INTJ has a friend he's drifting from that I hang out with when he does, which is like 1-2 times a year. They're an ISTP/ESTJ couple (the woman is the ESTJ, and she not-so secretly hates my INTJ), and an ISFP guy he's worked with a few times who's wife also not-so secretly hates my INTJ, but I've never met her, so she can't count.
Does that count as 5 best friends?
*sobs uncontrollably* Oh god, I'm so lonely!
