The terrible secret of two sisters.

I've always been afraid of my little sister.
I know that sounds kind of weird.
Jackie is two years younger and has always been an introvert, but she sees scary things.
Even now, at seventeen, she is still tied to her mother's apron, never leaves the house, and still sees something.
Everyone thinks she's special.
She always told crazy stories, and when we were younger, she would sometimes get me in trouble by telling our parents the weirdest things about what she had seen.
