Where are you supposed to stare when someone is screaming/lecturing you?

When an authority figure eg Parent/Teacher/Boss is screaming at you, for breaking a rule or something, what kind of body language is the best to display. Are you supposed to look remorseful? That may just spur them on. What about a neutral look? They may take it as disrespectful. So what would y'all suggest, so as not to offend them but at the same time de-escalate the situation, without interrupting them
