Summer death

As the woman was walking home from a store, carrying her groceries, she soon approached the stairs. But to her grief, she didn't know someone was following her all the time. Just as she reached the steps - a figure strode from behind, to push her, sending her flying down, crushing to the pavement below. It hurt, lying on the ground, the woman soon realized she couldn't move. She looked up, only to see the little red-haired girl of about 11 slowly and menacingly descending the very same stairs, taking the knife out of her pocket, eyes fixed on the woman.

"Why did you hug him..." she looked at her blankly, face's emotionless. "He belongs to me."

The woman didn't know this girl. Didn't know what she was talking about. But... she remembered, just a day before, someone stood near her family's house, looking in through the window. Could it be. But, the woman wasn't hugging anyone at that moment, except for her husband...

Eyes wide, the woman could only watch as the young stranger girl approached her, raising her hand with a knife.

"Die."

It was the last word she ever heard in her life.
