Extending the topic of power, control, and influence in the sibling relationship past the years covered in this issue is not an easy task because most adult siblings neither interact frequently nor live in geographic proximity, although there are considerable ethnic and social class variations. Thus, there are limited opportunities to observe how power is manifested, how siblings control each other and themselves to achieve their goals, nor how siblings influence each other. Comments in this commentary address the challenges presented when considering the trajectory of these dynamics in adult sibling relationships as well as the difficulties sibling dynamics present in carrying out tasks for which an egalitarian relationship is not ideal.
