Keeping personal space and quiet in public places is indeed an experience that many people want. If you want to reduce unnecessary communication when taking the subway, you can try the following suggestions. At the same time, please treat all staff with courtesy and respect: 1. Keep your eyes focused on the matter at hand: such as reading, using a mobile phone or wearing headphones. This not only allows you to immerse yourself in your own world, but is also often seen as a signal that it is not easy to communicate. 2. Use short and polite responses: If you encounter staff who need to communicate with you, use simple and friendly answers, such as "thank you" or "got it", without expanding more topics. 3. Maintain relaxed body language: For example, keeping a certain distance and avoiding long-term eye contact can convey the signal that you want quiet at the moment, but at the same time, pay attention to avoid being too stiff to avoid misunderstandings or unnecessary friction. 4. Adjust your mentality in advance: If you are used to staying alone during the journey and divert your attention by preparing a book, listening to music, etc., it will not only make you more focused, but also indirectly convey the signal that "I am busy at the moment". It should be noted that subway staff are trying their best to provide services to passengers, and appropriate and polite communication will help maintain good public order. Although you may want to minimize communication, it is still important to maintain basic respect when necessary. By following these steps, you can achieve your goal of reducing small talk without disrupting the harmony of public spaces.
