Computer Science homework help. one of the more interesting things about this chapter is the small group dynamics we exhibit, especially those that happen when we form our families. A dyad is a simple relationship between two people with one relationship to maintain, However, when you add a 3rd person, be it a child to a marriage or a 3rd wheel/friend to pair, there are suddenly 3 relationships to maintain. When you add 4th and 5th people to groups, the dynamics grow that much more complex.
