I don't assume that every reaction from someone else is related to me, nor have I ever done that. That's not what I was implying. I am sensitive and may take things personally when they were not meant to be from time to time, but not to a point where I think everything revolves around me. Quite frankly, I don't seek out explanations on most people's feelings or even need that kind of reassurance.
And yes, with age, even that sensitivity has lessened, as I think Si-usage improves and is not used in an imbalanced, negative way that beats yourself up about the past.
I'm talking about a feeling of alienation - everyone expresses a similar attitude, one which I do not share, or they easily grasp what is appropriate, which is less obvious to me. It's not that I am entirely in a bubble, but there is a bit of an obliviousness to these things and it does cause problems at times. I wonder why I am not succeeding in some area where others do, and because I focus on the underlying concept, I fail to see where I missed the Fe expectations for what is correct. This is not entirely in my imagination - I am not the only INFP who reports being viewed as odd in a negative way by others. Just as people can feel they walk on eggshells with Fi because its values are so hidden & nuances hard to define, I feel I walk on eggshells with the collective Fe, not understanding the nuances of its standards. Even when I think I get it, I still managed to fail. There's a delicate line to walk between observing others to understand these nuances and comparing yourself and then feeling defective.
From the INFP growth page at personalitypage.com...potential problems:
-May be unaware of appropriate social behavior
-May be oblivious to their personal appearance, or to appropriate dress
-May come across as eccentric, or perhaps even generally strange to others, without being aware of it
There are moments in which you become "aware" of it, and it's usually in some Si reviewing of what has been, and yes, it can be distorted a bit and focus on only the negative. Generally, this is not my default mindset, but it doesn't increase confidence when interacting with new people.
