The narrator plays a great role in the story to expose the unkind and uncivilized nature of the grown ups. The narrator of the story is a boy who presents the adults' world from his perspective. He looks into the adults' world and finds it ugly, unkind and uncivilized. He displays each and every unkind activity of theirs in the story. By presenting two different worlds in the story, the narrator persuades his readers that the adult's nature is unkind and uncivilized. He monitors their activities and finds them quite aimless and dirty. He observes them spending their time aimlessly in cards and drinks. They have a destination that they never try to reach. The boy observes them collecting funds for outing to Porthcawl, he observes their activities throughout the journey and mocks their time at 'The Mountain Ship', a bar. They are shown unkind to the narrator, the boy, who is left outside to look after the Charabanc while they drink their liquor in the bar. They don't understand that the boy also has feelings. In this way, the boy plays the role of a commentator and observer to expose the grownups' unkind and uncivilized nature.
