[⏵] Rituals of waiting: sitting on the bed, lying, sleeping. Routines of vigilance: searching cisterns, opening presents, reading letters. A young offenders’ prison on the Elbe island of Hahnöfersand. A few minutes by boat from Hamburg’s Landungsbrücken. Behind the walls, insularized lives in prescribed spaces, little echoes in from outside. »Who’s been keeping the corridor together?« asks a prisoner down the phone and answers his own question: »Since I left, no one!« A tortoise breaks out. A Beethoven string sonata begins. Time is locked in a cell, narrow and endless. Waiting and vigilance. What comes next?
