1) The story describes a situation where a group of children were playing near train tracks, with most playing on an operational track and one child on a disused track. A train was approaching. 2) Faced with diverting the train to the disused track to save most children but sacrificing the lone child, or letting the train proceed, most people would choose to divert the train for the greater good. 3) However, the story argues the lone child made the right choice to play safely, and hasty decisions are not always best when lives are at stake. Proper decision making requires considering all factors and consequences.
