At this time, you should remind him to turn off the sound. He wants a quiet environment. If he wants to listen to music, he can wear headphones.
If he is a rational person, then he will turn off his voice, mainly because of his personality. If he doesn't listen, that's his business. Let's just say it's his business if he doesn't do it.
We can tell him that you should put it outside. You can put it when no one is resting, and you can't put it when someone is resting. This will disturb others' rest, which is wrong.
If you really want to listen to music and watch movies, you can wear headphones, which will neither disturb others' rest nor affect your audio-visual effect. Why not have the best of both worlds? I think these people are easy to talk to.
If you really meet some outrageous people, then fight. Men don't listen to advice, they can only speak with their fists. There is nothing they can do.
I believe that other people in the dormitory must be on your side. If this kind of thing is said outside, others will stand on your side. Of course, this is the worst way. Don't use it unless you have to.
This will only make our relationship worse.
We said he wouldn't listen, okay, put up with it. We put on headphones to listen to our own music, and someone will stand up and say something about him. Of course, this is the first plan, and the second plan is to deal with a man as he deals with you.
When he is resting, play the sound of his mobile phone to see if he is angry and let him know what it looks like. Some people really do nothing. They don't know the seriousness and consequences of the matter.
When I first entered the university, I couldn't get along with one of them, which seemed unreasonable. While others were sleeping there, he put it outside his mobile phone. I was very angry, so I said loudly, can you turn off the sound? I am sleeping.
When he heard it, he turned off the sound. This time, next time, I really can't stand it. I told him everything I thought and told him clearly. I said, do you have a problem with me? If you have a question, just say it. Don't engage in these childish routines. Do you know it's impolite to play loudly when others are resting?
He may have been persuaded by me, and he also said it was a habit of his and would try to change it in the future. I'm not that angry, so sometimes it's better to show my cards. Don't go looking for this friend. What's wrong with it?
