1, seat endorsement type, I don't know if I can't hear the sound or feel quiet, but I am very energetic. Endorsement should not be in a quiet place like the library, but in the hall or corridor. Don't endorse in the library, you can't help but make a noise.

2, take a bite, you said it would be okay to eat in the library, I really can't stand the sound of yum yum (I have met people who can even drink yogurt, I don't understand.

3, couples are tired, then love to say that you can go out and find a tea shop to sit and chat? And really pay attention to your behavior in public, which is really speechless.

4. Seat-occupying type. I occupied a seat and put my schoolbag next to it. Obviously, no one came to sit, and I don't want to leave my seat to others.

5, book-turning, book-turning is particularly loud, which really makes people feel very noisy. I haven't considered the feelings of people around me in public. Do you think you can get high marks by turning over books and having a boiling passion?

6, shake your legs, shake your legs in the seat to make the chair make noise, forget it, some people shake their legs and even drive the table to affect the people around them, which is really annoying!

7. Chatting, a group of people came to the library to "study". A group of people came in chatting, sat in their seats and began to turn off the wheat. After a while, they began to chew someone's ear off and started fighting when they left. People around you are just being polite and don't want to disturb other students.
