I read it as a child and was very much moved by it.
Anne Frank famously said, "I still believe that most people are good at heart." Astounding faith in humanity. Maybe someday I will have such faith, but I'm not so sure.
I live in Poland, and have had to drive past Auschwitz many times. The place just looks sinister, with its spooky iron gate still bearing the lie "Arbeit Macht Frei".
When I speak with the locals about their time under the Nazis, my blood runs cold. It's eye-opening to be able to speak the local language with the people who live around Auschwitz.
I once picked up an old man hitchhiking on the road outside of Auschwitz, and he told me stories that brought tears to my eyes. Scenes he personally witnessed. His father had tried to save some potatoes for his family to eat, the Nazis found the potatoes, and the terrified children gasped as they watched a Nazi officer beat their struggling father nearly to death. The man I picked up hitchhiking was one of those children.
My father-in-law actually worked for the Wermacht in the kitchen as a young boy. They had him peeling potatoes. Luckily for him he was blonde haired and blue-eyed, so he did not get sent to Aushwitz. He was a "Nordic Type" for them, and so he lived. Still, they called the Polish kids in the kitchen "Kindershwein" (swine-kids).
To this day, he cannot stand the sound of the German language.
Ironically enough, we just found out that he is actually ethnically a German, thanks to some genetic testing my wife did as a result of her cancer.
