2. Going to the library or where to play has nothing to do with roommates; Similarly, don't be too curious about your roommate.

When your roommate is laughing while playing with his mobile phone, don't stand behind him and cran your neck to look closely unless he actively shares it with you.

People in the same dormitory may not get along well, even after four years, it may not change this.

5. Bring food and bread to others. Don't worry if others forget this little money. This is his quality.

6. After the WeChat chat, don't put your mobile phone directly on the table.

7. If you borrow small things like chargers and headphones from others, you must keep them safe. It's all right in the future, but remember to inform me in advance and don't lose it.

After studying for nearly twenty years, I still can't change the selfishness of some people.
