I wonder if this is why the Grimm's fairy tales and Aesop's fables have been so popular. Don't be the boy who cried wolf, lying too much means others won't believe you, the Tortise and the Hare about being careful to make time work for you.
It's only reasonable that children mirror and insert themselves, so it makes sense for these stories about children to give some lessons for the kids in a way that they gravitate towards learning from already.
