Hope allows you to come up with creative solutions to the disputes at the core of the conflict. 

Emotions play an important role in the conflict by altering how you appraise the situation. 

How many times have you made a claim about some piece of trivia only to realize, as soon as you’ve made that claim, that you’re completely wrong?

• A successful argument within a relationship remains compartmentalized. Don’t let it lead to questioning the entire basis of the relationship. 
• Don’t insult or degrade your opponent. Show that you meant “nothing personal” in the dispute.

If you appear to be giving the other side’s position a thoughtful review, then the solution you propose will seem to be far more sensible. Furthermore, your opponent may come to your side without you having to do anything other than listening.
