When Trudi takes on her role as a parent, these two subsystems help the family function efficiently, as the flow of information is regulated. Melissa remains in the sibling subsystem and there is no excessive sharing of information from the parent subsystem. Children can be children and not take on unnecessary parental roles. During times of conflict in the parental subsystem a breakdown occurs when the boundary between the two subsystems becomes weak as the mother and father overshare their conflict positions with their children. The father will turn to Melissa for support and the mother tends to look to her child for support. Members' responsibilities and boundaries are distorted leading to dysfunction at a time when subsystems are supposed to help the family maintain stability. This insight from my years of development helps me understand how important the boundaries between subsystems are. When boundaries become too permeable, the structure of subsystems within the family does not help the family function effectively. The experience will help me better convey, in an understandable way, the complexities of triangulation and how such triangulated relationships can be detrimental to the structure of the subsystem that helps a family stay in
