This chapter addresses the potential implications of mutual antipathies for children's experiences with the peer group as well as the behaviors and perceptions that may drive dyadic disdain. It raises four questions for consideration: (1) What are the demographics of dyadic disdain?; (2) How do enemy relationships relate to preadolescents' broader social adjustment?; (3) How do preadolescents with enemies behave?; and (4) How do preadolescents view their enemies? The results of an exploratory study designed to answer these questions are presented. (Contains 1 figure and 1 table.)
