So what is normal? The title of this book suggests a certain level of performance - being normal is an 'art' - which I thought was really interesting, as lots of theorists suggest that gender norms are just social constructs that we put on and play the part. The idea of social and gender norms is developed on the cover of the book where the traditional male and female icons (typically seen on the doors of public toilets around the world) are used to depict a girl breaking out of her masculine mould.
