A Cold-hearted Killer

Do you ever wonder..
"What is life?
Well,that was until I was born.
The thing is:
I was born as an undead child.
It was pretty hard to see how that can exist anyways.
Well,let me tell you a story.
Once upon a time,we were one whole race of humans.That was, until a rare condition came along.There was no name for it,so we called it The Idis.This condition made some babies who were born undead,causing them to have pale skin.But aside from that,we all look the same.Its really strange,because I was the only one born like this.For someone born with The Idis,I literally fit in with any human being I see.I have this best friend named Jack.Oh,by the way my name is Sally.Jack is human,and I am undead.He doesn't really care,as long as we're just best friends together.Jack and Sally.Sally and Jack.Best friends forever,together.
