A little, dirty puppy stood steadfastly on the rails, tail wagging with determination, amidst the bustling sounds of a busy railway station. Bystanders were concerned when the dog hesitated to move, his gaze locked on a spot beneath a nearby bench. Someone called the police because they were concerned about the puppy’s safety. As officers approached the insistent puppy, their demeanor changed from wonder to alarm. But he refused to move under any circumstances. They became pale when they discovered why.
