Nobody remembers their first school playtime. That day when the adults had gone. That day, I was in the playground. For eight years I filmed the same group of childen, asking myself: how do we grow under the gaze of others? As the years pass, the playtime games gave way to role playing; the "You're not my friend any more" gave way to the "you're not playing". One day I arrived late. Behind the cries, I could see them hitting Élise. How didn't I see it coming?
