Morality tales are short stories that teach a lesson about right and wrong. They often feature characters who face moral dilemmas, and the outcomes illustrate the consequences of their choices. These tales have been used throughout history to impart ethical values and encourage good behavior in both children and adults. Common themes in morality tales include honesty, kindness, and the importance of making wise decisions. Famous examples include Aesop's Fables, which use animals to convey moral lessons, and The Canterbury Tales by Geoffrey Chaucer, which explores various human behaviors and their implications.
