Some folk stories says that the fairy can steel the voice of the person who have see her.
Some times they allow humans to see and interact with them if thus humans are pure enough and spiritual enough.
That's why some times they show them self to children's or some gurus, magicians etc.
They are many theories about what is the origin of this species.
Some say that their are alliens, and other believe that they live in other dimensions.
i think that the second theory is the correct.
The fairies and the elves are living in other dimensions just like the angels the demons and the gods.
