Angel, Sorrow only befalls upon the living. Angels protect good over evil, each serves, fights, and protects for a different reason. They are all bonded by only One Great and All Mighty. We depict what we think they look like, for love, comfort, protection, well being, peace, and placed upon a tree. Even if we really don't see them, to feel we have been graced by their presences is a gift beyond measure.
