The key to maintaining polite but not excessive communication with the nanny in family gatherings is to set boundaries in a natural way while conveying respect and kindness. The following are specific suggestions： **1. Take the initiative to control the rhythm of the conversation** -Predictive response: "You have worked hard to take care of your children recently. You should try this dish more at the party today." (Pass the plate and divert your attention at the same time) -Time anchor method: "I'll go to the kitchen first to see the heat of the soup, you can eat slowly" (Each communication does not exceed 3 minutes) **2. Create a physically isolated space** • Seating arrangement: Direct it to the children's dining area to naturally form a social situation of "need to take care of children" •Task diversion: prepare simple handmade materials in advance, it is recommended that "the children especially want to do that origami craft with you" **3. Use social buffer strategies** -The third person intervenes: "Sister Wang, the pickled radishes made by Aunt Li are great. You can exchange your practices." -Topic anchoring technique: When we met, we took the initiative to say, "You will take more rest today. We mainly want you to try new dishes." **4. Combination of nonverbal signals** • Maintain a standing dialogue posture, holding tableware or drinks in your hand, ready to move at any time • Cooperate with nodding and smiling during the conversation, while the body is slightly sideways to the main area of the party **5. Structured exit dialogue** "I'm very happy to chat with you, but I have to go to ______ (pick up Auntie Sun/confirm the cake time/talk to Lao Zhang about medical insurance), you can eat more." **Key principles：** 1. Avoid using academic-related words and focus on role positioning (the dual identity of the waiter and the guest) 2. Keep a complete dialogue closed loop for each contact: open → maintain → end decently 3. Prepare 3-5 universal termination topics in advance: "Children's education/Hometown food/Weather changes" It is recommended to pass on thanks through small gifts or red envelopes before the party to reduce the pressure of on-site communication. If the other party continues to talk, you can use "You sit down first, I'll let Xiaoming tell you interesting things about school" to refer the conversation to a more suitable family member.
