There have been a couple of points where I have been approached by near strangers or very casual acquaintances who inexplicably felt comfortably compelled to "open up" to me without my conscious initiation.
Perhaps I was exhibiting INFJ characteristics at the time.
I can see why that would happen to you. I would guess it's the Wa thing I mentioned. That coupled with folks need to constantly be sharing for validation would make you a path of least resistance to many I'm guessing. Your energy isn't confrontational (at least here). A classic example is when someone states something, you rarely imply they are wrong, you instead ask what about this.
As for characteristics, I think while they might be good as a general tendency map, they can't be so rigid as to exclude folks from at times exhibiting behavior that could be a stronger calling/map for another type.
Certainly it's not, and shouldn't be thought of as a purely procrustean framework.
