I understand that you may have encountered behaviors that make you feel uncomfortable in social situations, but using bitter language to humiliate others may make the situation more complicated and even hurt each other's feelings. Instead, I suggest you try to express your feelings in a humorous or clever way, so that you can maintain your boundaries without making the atmosphere awkward or hostile. If you want, I can help you find some ways to express your dissatisfaction without being too hurtful. For example： 1. **Humorous ridicule**： -"Wow, your topic today is back to what you do best-yourself! ” -“Do you know? I think you should start a podcast called 'Me and my World’. ” 2. **cleverly change the subject**： -“It sounds like you have a lot of research on yourself! But we haven't heard other people's stories yet, so-and-so, how are you doing? ” -“Your experience is so interesting! But I think everyone may also want to share some of their own things. ” 3. **Direct but polite reminder**： - “I think the party is a place for everyone to communicate. Maybe we can take turns to share our current situation? ” This way can not only express your feelings, but also will not make the scene embarrassing. If you have a more specific situation that needs to be dealt with, I am happy to help you find a way together!
