My most unacceptable behavior in the library is littering, indecent behavior, self-concern, disregard for other people's feelings, and damage to the library. I think the library is a place where everyone is together, but there are some rules. First of all, keep quiet when you go to the library, and don't make too much noise to influence others. In such a good environment, there will always be people who do badly. Many people just litter and eat snacks in it. There are also some smelly things that seriously affect others' chances. Some people feel at home in the library and want to sleep. These are all bad behaviors. Also, when reading a book, they put the finished book back to its original place. Don't destroy the books in the library. I can't accept these acts of sabotage. In the library, we should know the rules. We should sit down and put the book back after reading. Go into the library to read and get books. After reading it, put it back. Don't throw it about. It is uncivilized to throw books about. We must stop these behaviors, which are unacceptable to others. In the library, there must be a library. So we hope that such a lovely person can see this answer and correct his behavior. The libraries are all together. Let's create and maintain our most beautiful library together!
