Some stories begin with "Once Upon a Time", but they are fairy tales and this is no fairy tale.
This story is about a family who looked normal, but who hid their true nature. They were somewhat like the old fairy tale that tells of the wolf who dressed like a sheep so he could go undetected in the flock.
As a child I was shy - not talking a lot. Instead I listened. Most of the time adults didn't realize I was listening to their conversations, but I was and I stored everything I heard.
Now, as an adult, reflecting on all that I know has happened in my family, those long ago, overheard conversations come bubbling into my mind. I now realize my family was not normal.
