Elie Wiesel said this quote

“ If I had spoken to him out loud, he would have understood the tragic fate of those who came back, left over, living dead. You must look at them carefully. Their appearance is deceptive. They are smugglers. They look like the others. They eat, they laugh, they love. The seek money, fame, love. Like the other. But it isn't true; they are playing, sometimes without even knowing it. Anyone who has seen what THEY have seen cannot be like the others, cannot laugh, love, pray, bargain, suffer, have fun, or forget. Like the others. You have to watch them carefully when they pass by an innocent-looking smokestack, or when they lift a piece of bread to their mouths. Something in them shudders and makes you turn your eyes away. These people have been amputated; they haven't lost their legs or eyes, but their will and their taste for life. The things they have seen will come to the surface again sooner or later. And then the world will be frightened and won't dare look these spiritual cripples in the eye. ”
