People react to conflict in different ways. whose strategy is the healthiest? mark explains his point of view in a calm and sensible manner and persists until the other person gives in. cecilia tries to have a reasoned discussion to get to the root of the problem and is always willing to find a middle ground. philip tries to make the other person understand his perspective and walks away before losing his temper if he can't find a resolution.

Cecilia's is the healthiest. Persisting until the other gives in is unhealthy and shows a lack of openness that's needed during a conflict. This is different with Cecilia, because she's always open to a middle ground, and not getting exactly what she'd like. Philip seems to think that having the other person thinking what he does is his end goal. The resolution should be something both parties are comfortable with, and getting frustrated and walking away instead of working it out isn't the best strategy
