The German army won’t let a soldier file a complaint and make a criticism immediately after a thing has happened. He had to sleep on his grudge first and cool off. If he files his complaint immediately, he is punished. By the eternals, there ought to be a law like that in civil life too – a
law for whining parents and nagging wives and scolding employers and the whole obnoxious parade of faultfinders.
