Roommate, always close the balcony door when the weather is hot, and eat heavy food to make the dormitory stuffy and smelly. If he doesn't let the door open for air, he will swear …

This roommate's behavior is really not very good. His behavior may be related to the habits he developed at home, so he may not be easy to change for a while. This behavior is that there is something wrong with his family education. It is estimated that his family's conditions are not very good and chaotic, so he has developed this habit. Roommates in the same dormitory can be coaxed. If he keeps swearing and swearing, you can ask the head teacher to change the dormitory, or you can open all the doors and windows to ventilate while he is away.
