Le Petit Prince

The Little prince is a charming children story about a young boy identifying quite strange behaviour in what appears to be quite narrowminded adults. I have done a quick summary below of some of these examples of the people he meets on other planets

• The Vain Man - Is lonely and craves admiration but only by being alone is he assured of being the richest and best-looking man on his planet.
• The Drunkard - drinks to forget that he is ashamed of drinking.
• The Businessman - the businessman owns all the stars. Yet he cannot remember what they are called and contributes nothing to them. 
• The Lamplighter - faithful but unhappy grownup, who is miserable because his job allows him no rest. His planet makes a full turn every minute, and in order to keep up, he is constantly lighting or putting out the lamp.
• The Geographe - well-read geographe, he refuses to learn about his own planet, saying it is a job for explorers. 

Seems these adult type people are just growing up on planets with no hope. Are all adults doomed ?
