This book investigates the biological and psychological function of crying, arguing that it serves as a fundamental mechanism for human connection rather than merely an expression of emotional distress. Judith Kay Nelson, a clinical social worker and psychotherapist, utilizes attachment theory to construct a framework for understanding tears across the lifespan. She examines the dynamics of crying within the therapeutic relationship, providing a clinical lens through which practitioners can interpret the communicative intent behind a client's tears. By synthesizing developmental research and clinical observation, the author posits that crying is an evolved behavior designed to elicit care and foster interpersonal bonds.

Experts in the field of psychotherapy recognize this work as a foundational text for understanding the clinical significance of emotional expression. Readers frequently note that the prose is accessible to both mental health practitioners and laypeople interested in the mechanics of human connection.
