The couples themselves represent the inconstancy and virulent nature of some marriages. The couples also represent the dichotomy of social vs. private lives in a marriage. People often put on "fronts" in public to make others think their marriage is well; however, it is a different story in private. Also, the portrayal of the couples' relationships smacks of irony as far as tearing apart the idea that marriage is a wonderful, centering, grounding institution. These couples are anything but centered and grounded! They fight, make up, fight some more, hold grudges, etc.
