I am generally good at understanding general social conventions and behaviours and determining quickly whether I'll be able to communicate with someone or should ignore them. I tend to be good at deducing how someone will react as well.
However, I am not good at making a good first impression, communicating properly and taking into consideration the feelings of other people even when I anticipate a reaction, I tend to fail at not provoking it.
I also take many things literally which infuriates people who think I am making fun of them or being picky about the meanings of things, they also think I'm playing stupid to irritate everyone. I can use sarcasm but often miss jokes and it leads to conflict.
I'm face blind and inattentive, sometimes Ijust don't see my friends in the streets or recognise them so people think I just don't care about them.
I'm pretty bad at using the theory I have in my head.
Not sure it's an iNTP thing though, perhaps because I'm too young.
