i have a brother who is kinda similar, it is nearly impossible to break his belief or atleast make him admit he was wrong for example, dont get me wrong he is smart and he knows alot stuff but he does bend the facts to fit his truth, and you could argue with him for awhile and even show him proof and he won't say he was wrong :D ohh and btw he will remember the truth and next time you bring up the subject that you were saying that and it was wrong he will argue and say that you were the guy who was wrong and he had the facts from the beginning, ofcourse he lies but yeah, he does everything to try and be the guy who is right and everyone else who goes against him is wrong or atleast in his mind is :D
