There is someone I want to type:
More likely introverted than extroverted.
He annoys practically everybody (not one of our friends. We know his girlfriend.) He is always trying to force his opinions on others. He needs to know a lot of things by heart and he is always certain that he is right. And he is ready to fight for it. He is an A-student, in a very difficult field in university. Unfortunately I don't know the type of his girlfriend.
An INTp is REALLY annoyed by him and doesn't understand how someone can be so irritating. They don't talk much, and the INTp sits and controls himself, but later wonders how someone can really talk so much bullshit.
ENFj gets slightly fired up when they talk. They quarrel quite a lot. And later that ENFj shakes herself and says, "grrr, that guy is SO annoying!"
I, an INTj (or ISTj) find him annoying and we sometimes quarrel, but not too often. We have discussions with no prospect ef ever finding an agreement and we change the topic. It doesn't get very fierce.
I considered him to be ISTj myself, but if I am ISTj in relationships, it doesn't make sense - my INTp boyfriend wouldn't be so annoyed by him. What do you think?
