What does the first chapter reveal about the narrator in the novel, The Little Prince?

In the first chapter, readers learn that the narrator was once an imaginative child who loved to draw. He drew a picture of a boa constrictor digesting an elephant. When he showed it to grown-up people, he asked if they were frightened. The grown ups were not able to see what he had drawn because they had no imagination. He tried to explain it to them, but he gave up and turned his mind towards more serious things. He decided to become a pilot when he grew up, which he did. He left his childhood ways behind him but never lost his mistrust of adults and their limited imaginations.
