When I felt ill and was on the way to becoming a burden to the other men, I noticed a growing chill in their attitude toward me. For people like us, living day and night on the brink of danger, the normal instinct of survival seems to strike inward, like a disease, distorting the personality and removing all motives other than those of sheer self-interest. That is why this afternoon I did not wait to go and tell my former comrades-in-arms what had happened to me. For one thing, they probably already knew; besides, it seemed unfair to risk awakening their dormant sense of humanity.
