What is the main conflict in The Little Prince by Antoine de Saint-Exupery?

The Little Prince is a fantasy about a pilot, stranded in the Sahara, who meets a small boy from another planet. The boy, who refers to himself as a prince, is on a quest for knowledge. The little prince asks questions of the pilot and tells the pilot of life on his own very small planet. This story is told in a simple fashion, as children's stories typically are, but it is not really a children's story. It is a story of a grown-up who has almostforgotten what is important. It is the story of the pilot's reconnection to his own sense of imagination and wonder. It is the story of the re-opening of the pilot's heart.
