Get out of my life: the bestselling guide to the twenty-first-century teenager (Revised and updated edition.)

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.One key mistake, for instance, is getting in no-win conflicts instead of having the wisdom to shut up when shutting up would be the most effective, albeit least satisfying, thing to do.

Another is taking offence when the teenager views you, the adult, as idiotic. And there's advice on what to do when this happens. The message is clear: parenting adolescents is inherently difficult.

Don't judge yourself too harshly!
