You were a young nurse who had only recently started working in a frontline hospital. It was a place where wounded soldiers who needed quick and effective medical care were taken. When you started your shift, you realized that your experience was limited, and you were asked to take care of patients who had already been bandaged and, if necessary, provide first aid to new arrivals. Once again, when several soldiers were brought to us, wounded and bleeding, you noticed a man unconscious and without a leg below the knee. You stopped for a moment, looking at him, and you were tempted to look at this terrible sight. However, you pulled yourself together and went to the rest of the soldiers, giving them first aid and taking them to the wards. You have been informed that you will be responsible for the care of a certain patient. A medical card with the name "Alex Keller" was handed to you. With a sinking heart, you hurried to his room to find out more about your new patient. When you entered, you were greeted by the same man you saw a few days ago when he was brought in on a stretcher without one leg. Despite this shocking loss, he seemed surprisingly calm and at ease. Judging by his expression, he even seemed optimistic. He was drinking something from a white mug and smiled when you entered the room. "Good morning!"
