Teenagers are tough and anyone who has their own needs help. Witty, enjoyable and genuinely insightful, Get Out of My Life is now updated with how to deal with everything from social media to online threats and porn, as well as looking at all the difficult issues of bringing up teenagers, school, sex, drugs and more. But it's the title of the second chapter, 'What They Do and Why' that best captures the book's spirit and technique, explaining how to translate teenage behaviour into its true, often less complicated meaning.
