Let them fully state their point of view about the issue/conflict/problem without interruption. What do they feel people misunderstand about them? What do they want or expect from others? 

The idea is to remain as neutral as possible. Just listening may be enough to allow someone to feel like they have the opportunity to say what’s on their mind. 

Inevitably there will be topics that represent points of disagreement and disharmony. Know what these topics are, and be extremely aware when these are brought up. 

Be prepared to address these issues in a direct, non-confrontational way or to deflect the conflict if the atmosphere becomes too heated.  

History and experiences should tell you that some subjects should be avoided at all costs. 

If your experience dealing with certain issues has left you stressed out or emotionally depleted, it's best to avoid the discussion until a time when both parties are willing to move it forward in a constructive way. 

Usually, arguments initially center around a specific topic/disagreement/response that made a person upset. If allowed to continue, the argument can become heated, accelerating quickly to personal attacks.

Make a concerted effort to imagine it unfolding before it actually does — and then nip it in the bud. 

Never allow any personal interaction or relationship to infringe upon or challenge your own well-being. 

Visualize your boundaries, that protective territory between you and someone else.
