1. Clear boundaries: Clearly define the relationship between the two parties as friends and avoid ambiguous or misleading behavior and language. Maintain politeness and respect in communication, without crossing the boundaries of personal space and privacy.
2. Moderate interaction: Maintain an appropriate frequency and depth of interaction, neither too distant nor too intimate. You can share interesting stories and troubles in life, but avoid delving into personal emotional issues to avoid unnecessary emotional entanglements.
3. Respect each other's feelings: Always pay attention to and respect each other's feelings and needs. If the other party shows discomfort or wishes to maintain a longer distance, one should adjust their behavior in a timely manner and give them enough space and freedom. At the same time, one should also have the courage to express their boundaries and expectations, ensuring that both parties can get along comfortably.
