Here are some polite ways to reduce conversations with the nanny at family gatherings: 1. **Focus on social interaction**: Focus more on communicating with family and relatives, actively participate in everyone's topic discussions, and naturally reduce the frequency of contact with the nanny. 2. **Find an excuse to leave at the right time**: For example, temporarily leave the current communication scene with the nanny on the grounds of refilling drinks for guests, checking the preparation of food, etc., and participate in other activities, and try not to return to the original conversation afterwards. 3. **Use polite excuses**: When the nanny talks to you, respond with a smile but answer briefly, such as "I'm chatting with my family here, please wait a moment" or "I'm a little busy now, let's talk later", etc., to show that you don't want to communicate, but it's inconvenient at the moment. 4. **Body language hints**: Keep a certain distance, reduce long-term eye contact, and don't show a particularly enthusiastic response, so that the other party can feel your social inclination. 5. **Direct the communication**: If the nanny chats with you, respond briefly and try to guide the topic to the entire party scene or other family members, so that the communication is not limited to the two of you, and then naturally transition to participating in other interactions. It should be emphasized that the nanny should also be respected and treated equally. Avoid showing contempt or deliberate alienation, and try to be polite and respectful.
