In Social Relationships: An Introduction to the Social Psychology of Membership and Intimacy Alan Radley
This book is an introduction to the fields of group dynamics and social interaction. It begins from the assumption that people live together in relationships which are personal, but also part of a larger social structure. The book argues that formal relationships and personal intimacy are not mutually exclusive. The author uses examples from everyday experience, and writes in a manner that should make the text accessible to a layperson.
