Upon opening first page of the book, carrying a humble atmosphere, the picture brings readers into a sincere world of a child who is shy in nature by simple and earnest language. In the aspect of the pictorial expression, the author takes geometrical patterns as the basis of picture composition and uses the disorderly zigzags as the basis of mental feeling. The simple composition to a proper extend heightens the genuine fear of a child: being afraid of facing the audiences, being afraid of failure, and being afraid of disappointment. Page by page, the overlapped zigzags concretize the worries and insecurity of a child. As for colors, the space is presented in bulks. Each page is dominated by a pair of complementary colors to emphasis the emotion of anxiety. In other words, it is painted bright but not garish to vividly express the enormous fear specifically belonging to the child. It is ingenious that when the geometric patterns and color bulks fit together, distant feeling and language are disclosed. This implicit distance echoes the aloneness that the girl has to face the fear by herself. The straightforward colors, lines and compositions seem simple, yet they present the deep and complicated emotion and feeling of children. In the aspect of the written text expression, the author selects the genuine simplicity to narrate and figure the feeling of the protagonist. As for the written text using, it is close to colloquial words, which enables younger readers to understand the meaning and get hold of the main point of the story easily as they listen to the text. Furthermore, when it comes to the collaboration of the text and the image, the author brilliantly captures the format of picture books. He lets the written text and pictures tell their parts of story respectively to present the consistent elements of time and space. By setting a storyline across thirty years, the author demonstrates that each of us has to respect our and other people's distinct temperaments. The story has a relaxing happy ending, but behind the happy ending it is a profound expectation of “acceptance and respect.” Everyone has his “the scariest day.” This sincere picture book not only speaks for adults but also knows children well.
