After lamenting the humor of this question, just give the answer directly.
First: Tell your roommate directly that you don't want to listen to your Fish Leong songs any more. Say that even if Fish Leong gives you all the courage, you can't play Fish Leong's songs outside. I really don't like and don't want to listen to your songs playing outside like this.
This directly expresses your true inner thoughts, and then you can see how your roommate does it and whether his roommate has enough self-knowledge. If he had self-knowledge, he would stop playing Fish Leong's songs outside at this time. Maybe he doesn't know himself, so he will continue to play Fish Leong's songs outside.
To tell the truth, this method is simple and effective, and it is mostly useful when meeting normal people, because no one in normal people will be idle and think about caring for others every day. Generally, this method can't cope, which either means that your relationship is not good or that the other party is abnormal.
Second, seriously negotiate again and clearly express your anger, saying that this is your final bottom line. I hope that the other party will not cross this bottom line like this. I especially don't like it. I hope the other person can stop, and then you can bring some threats. For example, if you keep playing Fish Leong's songs, believe me, you won't see the sun tomorrow, and then you can buy him some snacks to seduce you. As the saying goes, carrots make sticks.
In this case, you can basically deal with 90% of the people, because even people who have a bad relationship with you can feel your anger at this time, and no matter whether they are normal people or people who have a bad relationship with you, they will not risk angering you again and continue to release Fish Leong.
And at this time, you are a carrot and a stick, so more than 90% of people will achieve your goal at this time, and at this time, you have not endangered the other person's life, so that the other person can keep this life and live in peace.
However, there is no guarantee that this method is 100% effective, that is, the other party may be aimed at you, that is, if you are enemies, and at this moment, the other party is ready to break up and fight with you, but he has not taken it lightly, that is, you are insisting on conditions that will not endanger your life. Listen to me, don't be impulsive, don't endanger your life.
