This original and fresh approach to the emotions of adolescence focuses on the leisure lives of working-class boys and young men in the inter-war years. Being boys challenges many stereotypes about their behaviour. It offers new perspectives on familiar and important themes in inter-war social and cultural history, ranging from the cinema and mass consumption to boys’ clubs, personal advice pages, street cultures, dancing, sexuality, mobility and the body. It draws on many autobiographies and personal accounts and is particularly distinctive in offering an unusual insight into working-class adolescence through the teenage diaries of the author’s father, which are interwoven with the book’s broader analysis of contemporary leisure developments. Being boys will be of interest to scholars and students across the humanities and social sciences and is also relevant to those teaching and studying in the fields of child development, education, and youth and community studies.
