Growing up is a difficult task, perhaps the most difficult that children have to face: every day they encounter difficult situations, obstacles and feelings even toward themselves, which they do not yet know how to understand and which can lead them to lose self-confidence and become discouraged. Here then is a book, with pages that lead one to be curious about the many possible aspects of liking oneself, even with blue hair. A book that uses an artistic stimulus to open a discourse on growing up, believing in oneself, even with blue hair, and loving oneself, understanding that the inside and the outside belong to us. A book that leads us to open up to our imagination and relationship, to express our unique and beautiful emotions.A book in which empathy plays an important role.
