" I fished a cigarette from my pocket. After all, I had every reason to be content. I was not so badly off really; I had work, I was strong, I did not tire easily, I was healthy as things go.… But it was better not to think too much about all that—when alone, at any rate; and especially at night. For every now and then things had a way of rising up suddenly out of the past and staring at one with dead eyes. It was against such times that one kept a bottle of schnapps. "

― Erich Maria Remarque , Three Comrades
