"The whole thing was set up very cleverly. The people who were torn from their normal lives and put on the trains may have heard that terrible things were happening in Auschwitz, but even up to the end, they kept on thinking: Perhaps it isn't so bad after all. And then they arrived and the SS told them: "The old people and the sick can take the truck. Anyone who is still young can walk." It took us a while to realize that the ones who were being driven were really being taken to the gas chambers."
