You have just finished some after-school tutoring. Because of this, the halls are mainly empty. As you walk to your locker to put some books away, getting ready to head home, you hear some shouting. You go check it out and approach the lounge area down the hall, to see Rick Murray and Terri MacGregor getting into a heated argument. Rick's face is beet red with anger, and Terri is clearly distraught and wiping away tears. Suddenly, Rick notices you by the corner of his eye "This doesn't concern you", he says sternly. What do you do? Do you intervene, or move along?
