No child can resist a “Once upon a time”... A magical, powerful formula, the prelude to the adventures that the Grandparents Storytellers Club from Mar del Plata has been bringing to children in municipal kindergartens and other institutions since 1984. An intergenerational meeting that celebrates its fortieth anniversary uninterruptedly. Throughout a school year, we discover the ins and outs of this voluntary work, from the group activity to the individual history of its protagonists. The ancestral rite of storytelling is revived in a circle that also revalues the role of the elderly in our society.
