What exactly separates a friend from an acquaintance? Can men and women really "just be friends"? How do friendships change as we move from childhood to adolescence to adulthood? How can you support a friend in need, and how should you address conflicts and misunderstandings? This book answers these and many other questions readers may have about friendship. Books in Greenwood's series follow a reader-friendly question-and-answer format that anticipates readers' needs and concerns. Prevalent myths and misconceptions are identified and dispelled, and a collection of case studies illustrates key concepts and issues through relatable stories and insightful recommendations. Each book also includes a section on health literacy, equipping teens and young adults with practical tools and strategies for finding, evaluating, and using credible sources of health information both on and off the internet—important skills that contribute to a lifetime of healthy decision-making.
