How to express your dissatisfaction with playing music outside your roommate's dormitory gracefully and politely?

Just tell him gently, don't worry too much. This kind of thing, if you want to be elegant and polite, will definitely not play a role in expressing dissatisfaction. If you want to express your dissatisfaction, tell him that you don't agree with his behavior of playing music outside. There is really no need to consider elegance and politeness because of this.

In fact, this kind of small friction is particularly common in our daily life, especially in university dormitories. Of course, everyone comes from all corners of the country, and it is not easy to get together under one roof, but some of our living habits or behaviors are definitely different, and may even cause some unnecessary minor troubles. I think at this time, as long as others do something wrong, and their bad behavior has violated their own interests, there is no need to care about politeness and elegance. Just tell him simply and directly. If you care so much, you won't get the effect you want.

When we first moved in together, there was a little contradiction because of these problems, but at this time, we need a middleman who is not worried about offending people to stand up and talk about the existing problems. This middleman is definitely not elegant, because those elegant and polite people in our dormitory, generally speaking, can tolerate whatever happens. Even if this happens, people generally don't care, and at most they turn a blind eye.

So, that's why I said, you can't solve the problem if you are elegant and polite.

If you really can't stand it, tell him. Anyway, as long as you infringe on your own interests, you should talk well and tell him that you are not doing well.
