It is the fire shut up in the flint. A multiple personality is in a certain sense normal. A person should not promise to give a child something and then not give it, because in that way the child learns to lie. It simply files things away. It keeps things for you, or hides things from you - and summons them to your recall with a will of its own.
Some people hear their own inner voices with great clearness.
And they live by what they hear. My hope is that gays will be running the world, because then there would be no war. Just a greater emphasis on military apparel. A bad day by choise.
