I tend to kinda...stare "through" the world a lot of the time. Liek, y'know, in that Ni-dom way?
This is the case often when I'm involved in a social interaction I'm not really "into"; like, I don't know, during talk about matters I consider unimportant, or when the pace of the interaction's too slow, or there's just no "spark" between me and the other person. It's like, "no, this isn't what I'm looking for, so I'm just going to absent myself nao and [mentally] go off somewhere more interesting."
On the other hand, when I'm into another person and/or a topic being discussed, the eye-contact's all there, wholly engaged and absorbed, seeking for/establishing connection, pushing for
more, more, more of this.
...This pattern seems rather Sx/Sp-related?
Don't pick up on details of body language etc so much, at least not consciously (retarded Se, I'd guess?). Even when I was at my most socially anxious I didn't pick up overly on visual cues, it was more tied up with compulsive over-interpretation of every utterance into it's possible meanings/interpretations.
