That is the way we decided to talk, free and easy, two young men discussing a boxing match. That was the only way to talk. You couldn't let too much truth seep into your conversation, you couldn't admit with your mouth what your eyes had seen. If you opened the door even a centimeter, you would smell the rot outside and hear the screams. You did not open the door. You kept your mind on the tasks of the day, the hunt for food and water and something to burn, and you saved the rest for the end of the war.
