" In these examples, triangulation becomes a defense. Triangulation becomes a way to offset the abuse of power and to get clarity about the wrongs committed. This kind of triangulation occurs in families where one member is abusing his or her power. Like a poor boss, an abusive parent who is deaf to protest gives the children no choice but to talk about that parent. When a parent refuses to hear the issues of adult children, the children turn either to each other or to outsiders, but both sides lose. The parent loses an opportunity for greater closeness with the child and the adult child must grieve the loss of the sought-for resolution that cannot come about. "
