The Faerie Folk are the masters of disguise as they travel, work and live within the boundaries of our mundane world. The bird sitting on a branch watching you, the squirrel scolding you from high up in a tree, the leaf scurrying quickly across your feet . . . any of these could be a Fair Folk in disguise.
The Faerie Folk love a good masquerade, or perhaps it is just that our eyes see only what our mind allows us to see. If we can open our minds to the possibility of the existence of Fair Folk, then perhaps our eyes will finally see the truth behind that leaf moving quickly across our yard.
