The fox is one of the main characters; he teaches the little prince the secret of life. The little prince is looking for friends but does not think the fox could be a friend. The fox explains friendship to him as a process of “taming” each other. They create ties and share life together, and that changes everything for each of them. He will not regret when the little prince leaves because he will still have the color of wheat reminding him of his friend’s blonde hair. The fox shows him that the essential nature of life is invisible and can only be experienced through the heart. Love creates a sense of responsibility.
