I had in mind a case close to my family, friends of my parents, who seemed to be the perfect bourgeois family, and a young boy, who when he was 17, committed suicide. It was such a shock. The parents didn't understand. Nobody understood why he did that. Everybody was exploring his life, trying to understand what the problem was. Everybody had a feeling that this guy had the perfect life: he was beautiful, he was clever... but he did that. I had that in mind, about Isabelle in Young and Beautiful, for the parents to see adolescents like aliens.
