Without her, I am uprooted. She is Rosine, my maternal grandmother, my “irresistible” whom I loved passionately. This attachment, she returned to me a hundredfold. Tenderness, listening, patience, exchange, transmission... Many of us structure our adult life thanks to what our grandparents brought us. Because the strength of this intergenerational bond echoes in many of us, Nathalie Levy was keen to tell about these gray hairs, these wrinkled faces, these outdated words, these outmoded ways but above all these links, this heritage, this sediment founder by collecting testimonials from people you love. Singers, actors, authors, athletes, industrialists, chefs have agreed to open their memory drawer and reveal their unique relationship with a grandfather, a grandmother. Their stories are amazing, intense, funny, moving, respectful... And oh so necessary!
