They are called the Fay, faeries, sprites and pixies...All of one sort. Mythical, spiritual, intriguing little beauties. Are they real? YES!
While most people can't see them, some do, especially children. Some people see actual fairies, and some see a white misty shape, other people see colored lights and some sense their presence. Fairies are the spirit of nature, they flit around and pull your hair across your face while you garden, they sit on the brim of your hat while you rest, they follow behind and flip up the blades of grass you carelessly trod down.
Fairies are of days gone by, far to delicate and misunderstood to ever be a visible part of this world anymore.
