Do you know what a fable is well its like a folktale, fairy-tale,and kinda like a myth. Kinda like The Boy Who Cried Wolf,The Ants and The Grasshopper,and Aesop's Fables witch has millions of fables in it. Fables they usually don't end very well like in the Ants and The Grasshopper the grasshopper dies, and The Boy Who Cried Wolf the boy got eaten by the wolf. Its to teach kids a lesson back in back in the old days to do there work sometimes or to scare them.
P.S you should start reading more fables/myth/folktale/fairy-tales.
