Moreover, when someone speaks loudly in the library, there will be that kind of bored eyes around him. At this time, he should feel it and be restrained. At this time, because of his personal reasons, it has caused public anger, and he dare not have any opinions. If he plays dumb, he can go directly to him and pat him on the shoulder, and whisper to him, please keep quiet, everyone is studying. If he is quiet for a few minutes and starts quarreling again, he can contact the librarian and tell the librarian the situation.
Let the librarian talk to him, or ask him out, or take him to a separate space, so as not to interfere with others' reading. If he ignores the librarian's reminder and continues to make a scene there, there is no need to give him face at this time. You can tell him directly, classmate, please keep quiet, everyone is studying.
Because some of his previous behaviors have aroused the anger of most people who study in the library, and he doesn't listen to the arrangement of the librarian, then at this time, you stand up for everyone. If he is still reluctant, or if he dares to be fierce, other people in the library will stand up for you at this time. That noisy classmate dare not do anything to you. But in fact, everyone goes to the library to study and get to know each other. Sometimes it may be a little careless and louder, but a simple reminder will be lower.
