If you want to avoid engaging in complex conversations while shopping, you can try the following strategies: 1. **Simple greetings**: Use simple greetings such as "Hello" or "Good morning." 2. **Explicitly state what you need**: Tell the store directly what you need to buy to reduce the chance of small talk. For example: "I need a bottle of water, thank you." 3. **Polite response**: If the store clerk tries to talk to you, use short answers such as "yes," "no," or "thank you." 4. **Avoid open-ended questions**: Do not ask questions that may lead to complex discussions. 5. **Focus on the shopping process**: Focus on selecting products and checking out to reduce the time of conversation. 6. **Wear headphones**: Pretend to listen to music to reduce the chance of others trying to start a conversation (make sure this does not affect communication). 7. **Ask for necessary information**: If you need help, you can ask directly, but keep the questions simple and clear. In these ways, you can more effectively control the depth and length of the conversation.
