I never could troll – but I like the psychological side of it. I only skimmed through the “please understand me” books and I don’t remember if one or both were INFP, but since i was, and THEY were and came up with the 16 type system – maybe *i too* could do it.
and i could. the Sensor was easy as my mother is ISFP : I just had to think of our differences.
i’m on the line with i/e and t/f, so I didn’t have problem with that so much.
but the j and p were really really hard for me.
I simply couldn’t tell them apart but i eventually did.
