I understand that you are dissatisfied with that person's behavior. Sometimes facing someone who is bragging can really make people feel uncomfortable. However, using mean language to satirize others, although it may relieve you in the short term, in the long run, it may exacerbate contradictions and even make you feel uncomfortable yourself. Instead of fighting back with mean language, it is better to try to deal with this situation in a more mature and constructive way. Here are some suggestions： 1. **Stay calm**: When the other party is bragging, stay calm and polite, and don't be irritated by his behavior. Your calmness may make him realize that his behavior is not welcome. 2. **Humorous resolution**: Responding to his boasting in a humorous way will not appear mean, but also make him realize that his behavior is a bit excessive. For example, you can smile and say, “Wow, it sounds like you are really omnipotent!" ” 3. **Direct communication**: If you feel it is necessary, you can communicate with him privately to express your feelings about his behavior. Tell him in peaceful language that his boasting makes you feel uncomfortable and may make him reflect on his behavior. 4. **Focus on yourself**: Focus on yourself and focus on your own growth and goals, rather than being disturbed by the behavior of others. This will not only make you happier, but also make him realize that his boasting has not affected you. If you really want to express some sarcasm, you can try to use some witty but polite ways, such as： -“You are so good, many people must envy you, right? ” - “Listening to you say that, I feel that you are really omnipotent. I admire you. ” -"Wow, you are so good, I'm a little embarrassed to talk to you. ” These words can express your feelings without being too mean. Hope these suggestions are helpful to you!
