By supporting and influencing their families and communities, grandparents-and those who act as grandparents-can play a key role in today's society. Their special mission is derived from a strong sense of purpose and direction that develops from making significant contributions to family life. These include compiling and recounting family histories, maintaining meaningful relationships among different generations, opening up family communications, explaining social changes, and participating in community life. With the aid of real-life examples of intergenerational family dynamics, the author-a clinical sociologist who has practiced family therapy for more than 25 years-presents principles, techniques, and perspectives for today's grandparents.
