In college life, a large part of time is spent with roommates in the dormitory, and everyone will have some minor frictions. Especially when I have just been assigned to a dormitory, I don't know them yet, and there may be some conflicts in my personality. If we are polite in the dormitory and respect the behavior habits of other roommates, we will minimize the friction with roommates. Similarly, when we feel polite and have an attitude, roommates will naturally put down their posture and get along calmly.
