Step-by-step explanation:
In a negotiation where your relationship means less to your opponent than it does to you, the best way to proceed would be to remain less attached to a particular outcome and be prepared to follow their lead. This approach allows you to maintain flexibility and adapt to the situation, rather than holding firm on your initial offer or making excessive concessions. By being open to different possibilities and focusing on finding mutually acceptable solutions, you increase the chances of reaching a satisfactory agreement.
