Canine Compass
The other day, I watched a man wandering blindly on the train platform. His guide dog, sniffing the wind, led him in circles, until at last the man asked, or rather, told a big guy "I'm gonna need you to help me." The big guy escorted the pair to the edge of the parking lot, where the dog resumed his rootless orbit. By then, I'd boarded my train. As we pulled away from the station, I searched among the parked cars. They stood there still, a man and his dog.
