I found the answer to my question about explaining reality it a girl that was raised on fairy-tales!
How do you do it?
You raise her with a different version of the story!
I think this approach is fantastic.
Because “happily ever after” is not the end of the story,
We know a father who understands the fairy tale phenomenon. He tells an alternative version to his three-year-old daughter that ends something like this: “Cinderella and the Prince courted for a year and became very good friends. Then they married. They lived a very simple life and worked for social-justice issues to end the oppression of the poor. They didn’t live happily ever after, but they did learn to love each other deeply . . .” He also tells her how Cinderella traded in her glass slippers for hiking boots so that she and the Prince could hike all over the country.
