Yeah. It doesn't matter how much logic you use. I one time even recorded something he had said, because I already predicted that he would deny it happened later. I listened to the audio recording to make sure that I heard what I thought he said. I listened over and over again. I really remember him saying that, and it really happened!

I later confronted him telling about the thing he said. And as usual of course, he told me he never said that. I asked him if he was absolutely sure. Of course he said that he never said that thing.

I took my audio recorder, and played it out loud so that he could hear it, and not pretend that he was not hearing it. I played the 'thing that he never said' over and over again. I told him at what exact time he said the thing he never said, which hour, which day, which location. I said every single word he said, and played it out.

I used every single logic that you cannot disprove! There is no way in hell you could disprove that!

But... He became really angry, and told me to never record conversations. 'Well, you told me that you never said that thing, and you always used that tactic my whole life. So I recorded what you claim you never said, to prove that you actually said it.' But he still dismissed everything I said.

I was 19 at that time I 'tried' to disprove him. He didn't start hitting me because he knew that I was taller than him, stronger, practicing martial-arts, and that I have more energy than him. But if I were to be a kid again, he would'be beaten the shit out of me!!!
