I'm just gonna be blunt here, I am cursed (or gifted?) with having very little interest in the lives of others, because my own life is something I find incredibly interesting in itself. I often ask for advice from others, and there are many people who do enjoy helping me out and offering assistance. I appreciate their help, and they're glad to be of help. I can certainly see how this could be viewed as "the dj arendee show" though.
As far as connecting with others and putting up a wall, I very rarely connect with anyone. I actually can count the number of connections I've had with others on my fingers. I hate to quote theory directly, but the Sx instinctual description was right on the money when it said the only reason I become social is to find my soul mate. Once I find this person, I disappear from existence with them by my side. All popularity is ignored, etc.
Oddly enough I feel the same way you feel toward me, toward anyone with Fi Ne Te and Si in their function preference. I feel like STJ's and NFP's sole purpose is to have everyone recognize their presence and get offended if you do not recognize their presence. I've had a lot of ESTJ's tell me I'm arrogant because I don't make eye contact with them. No where in the rule book does it say I need to make eye contact with anyone.
I would first suspect my function preference is to blame. What you may view as "interpersonal communication" I may value as a waste of time in my search for Ti system building.
