A large woman who walks slowly down the street. The combination of her large size and slow speed make it difficult to pass her on a standard sidewalk.
A normally
paced walker will easily catch up to the slow and
wide walker, but, unfortunately, it will be nearly impossible to pass the slow and wide walker because the sidewalk is too narrow. The normally paced walker will have to stop to give the slow and wide walker space between the two
walkers. Then the normally paced walker will catch up again, thus repeating the cycle. This repeated stop and catch up and stop action is similar to a
toad is hopping slowly down a sidewalk.
Charles
Wellington IV was late for his important
Madison Avenue appointment because he got caught behind a
toad off the subway. He could not pass her on the busy street, and the toad had no inclination that there was a man who was walking like a normal person behind her.
