In public, everyone has the right to choose their own way of socializing, but at the same time they need to respect the dignity of others. Here are some suggestions that don't hurt the feelings of others while maintaining proper social boundaries.： **1. Maintain a polite but concise response** -Nod and smile, then move forward naturally, no need to stop -Replace small talk with short greetings such as "Hello/hard work" -Continue walking after waving your hand to avoid forming an opportunity for dialogue **2. A physical method of creating natural distance** -Wear noise-canceling headphones (music can not be played) -Maintain a stable pace to avoid retention -Check mobile phone information in advance to create a sense of busyness **3. Bottom line that needs special attention** -Avoid discriminatory actions such as showing expressions of disgust or covering your mouth and nose -Don't say insulting words such as "go away" when you refuse to communicate -Should not ignore the active greetings of others **A perspective worth reflecting on：** Career choice and education level cannot define personal value. Many construction workers have superb professional skills, and some of them continue their studies through night school. Treating different occupational groups with an equal attitude is not only the benchmark of a civilized society, but also the embodiment of personal cultivation. If you do encounter an overly enthusiastic conversation, you can politely refuse for objective reasons such as "in a hurry for a meeting". It is important to maintain the basis of mutual respect and avoid turning professional differences into social discrimination.
