Cuando los abuelos se mudan a vivir al campo Clara se pone tan triste que todo empieza a irle mal: su amiga Marta se aleja de ella, su madre ya no la entiende y el abuelo la ha abandonado. Todo es horrible y no consigue salir de su tristeza. Pero el abuelo le hace entender que su tristeza le ha impedido ver el apoyo que los otros le estaban dando y que la felicidad de los demás no debe hacerle daño, sino hacerla más feliz. Al final del libro se incluyen notas para padres y educadores. When the grandparents move to live in the countryside, Clara becomes so sad that everything starts to go wrong for her: her friend Marta moves away from her, her mother no longer understands her, and her grandfather has abandoned her. Everything is horrible and she can't get out of her sadness. But her grandfather makes her understand that her sadness has prevented her from seeing the support that others were giving her and that the happiness of others should not hurt her, but rather make her happier. Notes for parents and educators are included at the end of the book.
