Final exam is going to start soon. Maybe our library is going to be crowded, and it will be noisier than before. In this situation we try to act more carefully. But some people don’t do that. They interrupt people’s concentration. First, they use their cell phone too much. Of course most people sometimes use their sell phone at library. But they don’t put it on the desk, and they don’t make any sound. Second, they deal with books too tough. For example, when they turn a page, it’s harsh to the ears. Finally, they talk to their friends. They think it’s not noisy, and they talk very low. But that’s not, so we have to try to make a good circunstance at library.
