The age lie at the Birkenau selection
In 1944 at Auschwitz-Birkenau, twelve-year-old Ruth Klüger stood in a selection line for a labor transport. A young woman prisoner working as a clerk whispered to her to claim she was fifteen, then argued with the SS officer on her behalf, and he let her through. That transport took her and her mother to the labor camp at Christianstadt, and Klüger treats her survival as hinging on one stranger's unexplained, unrepeatable act of goodness rather than on anything she did.
