Well, now the topic on my bro.
Im not sure, I htink he is INFP but not really sure yet.
He is more introverted than extraverted, i think (even though he is well socialised.
He is as lazy and unfocused as a P.
He is attracted to abstract arts, he is artsy (musically and visually). He is attracted to stories like the lord of the rings, narnia, and other stuffs likes this with elfs, mindgets, wierd woods and magical environnement. I think, this might rather be an INFP trait.
BUT he far from being the lovey-dovey INFP. He is nice, sensitive, able to implicitly read people and give advice on how to talk to them. But he is also able to say very harsch things with a rare sense of formula. For example, he is an absolute fan of Dr House because Dr house also has this way to say harsch things well-said.
He also loves to debate for the pleasure of debatting (that was our favorite game when we were younger)
