Yes, well it was- he [Rudi Vrba] was unrecognisable [after his experience in Auschwitz] because he was a sort of very attractive young boy. Trusting and with a wonderful sense of humour before. And very sort of… engaging person. And then when I saw him again, there was tremendous change. He looked quite different. And not only because he was two years older and strong and muscular, but it was in his eyes that was sort of quite different.
