Is it possible for one to have an extraverted function and be extraverted but not talk much? I swear that I know this kid and he loves hanging out with people all the time and gets energized by conversations, but he rarely speaks! His voice isn't too loud either. Is he an extravert? I can picture this dude hanging out at home reading a book or something, but he's always with people! Is this combination possible to be defined as antisocial extravert?
List other weird possibilities of MBTI if you must.
