The premise of this question is based on a possible stereotype or phenomenon. When discussing this situation, we need to note that everyone is an individual and should not presume a certain judgment or sense of distance based on occupation or educational background. The need to maintain distance in communication may be due to personal preference, cultural differences or specific situations, rather than based on the other party's occupation or education level. If you feel that you need to maintain distance when communicating with the delivery person or anyone, you can do so in the following ways: 1. **Respectful and concise language**: When communicating, be respectful and polite, and use concise and direct language to express your needs or thanks. This can help you convey your message while avoiding too many personal topics or in-depth conversations. 2. **Avoid too much small talk**: If you are not good at or do not want to engage in small talk, you can politely focus on the transaction itself, such as paying, checking orders, etc. This can keep the focus of the communication. 3. **Use technical means**: Now many food delivery platforms support online payment and order management, you can use these technical means to reduce direct interaction with the food delivery person. 4. **Set personal boundaries**: At any time, if you feel the need to maintain distance, you can politely decline further conversation or directly indicate that you are in a hurry. It is important to note that your attitude and behavior should always be respectful and polite, regardless of the other person's occupation or educational background. Everyone has their own life story and struggles, and maintaining a positive and respectful attitude can help you build better social connections and interpersonal relationships.
