Yeah, activity relations are no good imo. But depending on subtypes either pseudo-duality or pseudo-benefit can occur which can improve or worsen relations. I get along better with irrational subtype EJ in general. But most EJ I find annoying with all that tension and excess energy.
I get along well with EP, except too strong irrational ones lol. ILE-Ti and ILE-Ne are like night and day. I don't have any complaints about SEE even though they're my super ego. Maybe they confuse me with ILI lol. Irrational EPs have so much energy that they're the ones dragging me around
With IJ I get along fine except EII and ESI for obvious reasons lol. Works better with irrational subtypes. I've had quite a few LII-Ne and even EII-Ne friends at school. Mostly cause Ne egos were the outcasts so we had to look out for each other lol
Then with IP I get along even with ILI. My closest friend is SLI-Si. Works better with rational subtypes. Irrational subtypes are too relaxed and sluggish imo, they never really want to do anything. Rational subtypes are easier to get moving and generally receptive to my random activity ideas lol
My problem with EJ is that they are so planned and undeliberate that you can never tell them "hey wanna hang out today" and expect them to say yes. Everything they do needs to be scheduled days in advance and by that time I'm interested in doing something else. With IP it's more like "hey wanna hang out?" "sure" "ok, be there in 5" and that's it, no scheduling or excuses.
