When you're out in public and you observe a potentially dangerous/bad situation, what do you do? Do you interfere? Or do you pretend you didn't notice and keep going, along with the majority of people?
Scenario 1
A crowded subway car. I'm standing by the door, as usual. A middle-aged man and woman are inches away from me. The man has his face in the woman's. With steely eyes and jaw clenched tight with hate, he's muttering horrible things at her, his eyes locked on hers. This monologue goes on for a minute or so, her face grim, emotionless and unresponding. I decide to interfere. I say, "Is everything ok?"
