In history you read about elves, fairies, little people, spirits. It was an accepted part of reality.
But now that’s obvious nonsense and if you see fairies then you need a doctor.
Are we insane now?
Yes I know, nutrition, literacy and the scientific enlightenment. But still.
We used to tell stories about seeing fairies and so.
We still tell stories about seeing fairies and so on. Nothing has changed.
I myself have only really encountered a fairy one time.
