I accepted his criticism calmly at first because I knew he was only trying to help, but I felt so vulnerable, so exposed, that I
had to attack him after the numbness faded away -- I immediately went to sleep after the whole ordeal, dreamed about fighting him back word-for-word, and woke up to immediately enact that dream, not knowing that he was in a bad mood, and too bothered to even care. I was piqued because what he said was the bleak truth, so my counterattacks on him revolved around persuading that the truth was otherwise, even though I was fully aware that no persuasion would change his knowledge of it.
We view each other as the confidant of the other, and are very similar behaviourally. I think I started blowing off my relation after that incident, though, by always trying to prove myself to him. It's a strain to get him to elaborate on "I don't know" answers, but I admire his way of "just knowing" things about people and condensing entire paragraphs from me into single sentences. He uses his understanding of people to adapt to them, and doesn't know who he is because he can assume so many personas. However, he can give the greatest advice on how to deal with people, like methods to placate my mother, for example.
We both feel exposed outside the safety of our rooms (or just, when outside in comparison to being at home), but he can really take some things to the extreme. It's hard for me to digest how he could possibly go for days without food, and even longer without sleep because "it's inefficient". And he doesn't mind having his room tidied as much as I do. We "tend to override each other" when communicating. He feels inferior to those with greater skills, knowledge, and intelligence, but he doesn't feel threatened by the same people, in the same way -- if anything, I've been surprised by how he'd view someone whom I consider a threat to be "inferior" to him... Damn, I think
he's the INTp, because based on what I've "extracted" from him, his concern over knowledge could fit Kristiina's explanation:
Now I remember that Extraverted Feeling creative types can be very concerned about their public presence, which can sound like Fe-PoLR. Using the same logic, that paragraph does not indicate Te-PoLR after all.
When I asked him why accumulating knowledge was good, he explained that it's "stimulating" and fun in that it
can be applied to impress others and prove others wrong. I feel that creating a good impression on others is really important to him, and his constant mirroring of others may be attributed to that. I could never successfully type him because his emotions run so much deeper than mine that it could be burdening (just as much as my total dependence on him burdens him, I'd imagine). But I can definitely see myself as his beneficiary. And he will kill me if he ever sees this thread

I am so going to get kicked for my display of submission
And onto sleep.
