Method 1: Habit. Don't care about other people's opinions, you can play with people in other dormitories. Your mouth is on others, and what others say is others' business. Just be yourself.

Mouth grows on others, ears grow on yourself, it is their business to say or not, and it is your own business to listen or not. Think of it as the background music of this life movie.

Method 2: communication. If you really care about other people's opinions and eyes, then you can show them your cards and see where you are doing badly, which will lead them to isolate you. Others can't isolate you for no reason. People must have their reasons for isolating you. Then communicate and find out the problem.
