In normal life, try to associate with these people as little as possible. Because they are narrow-minded and have some "little people". Get along with people with good grades, improve yourself and make yourself better. There is no need to punish yourself with other people's mistakes. Now that we know the "true colors" of some people, there is no need to continue to get along with them. But after all, because I am a classmate, sometimes being deaf is also a good thing, so I can relax my mind.
