Arrogant and rude person. No matter what the problem, no matter whose fault it is, he will not admit that it is his own problem. He will blame you for everything, attack you with insulting words, and describe you like an idiot. In his eyes, it seems that he is the only one who has a brain, and the others are all idiots. If your explanation doesn't match the answer he wants to hear, he will shame you. He only wants to hear the answers he wants, not the facts.
