I didn't really understand why until I was drunk once myself. Actually, people who are not drunk don't want to admit that they are drunk. They don't justify themselves for the sake of face, and they don't dare to admit that they are drunk, but they don't know the situation at all when they are drunk. He can't tell whether the people around him are drunk or he is drunk, because he is still conscious and knows everyone around him, so although he is drunk, he can hardly speak. Although he was drunk, he was sober, so he really thought he was not drunk at all. You are absolutely strongly opposed to people who say you, so you feel this way.
Because I felt this way the last time we were together. I'm sober, my head is heavy, and my speech is incoherent. But in my heart, I am simple. I'm not drunk myself. Instead, I feel that everyone around me is drunk and they refuse to admit it. Anyway, I feel that those who walk on the road are drunk, and I can see them fall when I walk. That kind of feeling is really only realized after being drunk once. Anyway, I know I am drunk, but it is absolutely unacceptable to say that I am drunk. As long as a drunk person can still act, he doesn't think he is drunk at all, because drunkenness has no pain or other obvious feelings to remind them, so as long as he is sober, they won't think he is drunk.
This is really my personal experience. That time I was drunk, unconscious and slept for several hours. Although I am very uncomfortable, my mind clearly controls myself to walk without shaking, and I know exactly what to do. But when I see someone passing by on the road, I instinctively think they must be drunk, because I see them swaying. Although I have drunk, I still know how to try to control my trembling, but I can't control myself when I see them, so I don't think I'm drunk. From then on, I can finally understand that those who are drunk can't admit why they are drunk, because although he can't move, he knows that he is drunk, so he won't think he is drunk.
