You have always been the most ordinary soldier, no high achievements, but no lag behind everyone else. You stand proudly in the middle among them, and it hardly bothers anyone. Your discipline is within normal limits, your strength is within normal limits, and Captain Levi is paying you exactly the attention he would normally pay to a soldier.
