“This habit of getting used to things is the reason that we seem to forget so quickly. The day before yesterday we were still under fire, today we are fooling about, seeing what we can scrounge around here, tomorrow we’ll be back in the trenches. In fact we don’t really forget anything. All the time we are out here the days at the front sink into us like stones the moment they are over, because they are too much for us to think about right away. If we even tried, they would kill us. Because one thing has become clear to me: you can cope with all the horror as long as you simply duck thinking about it – but it will kill you if you try to come to terms with it.”
