Play With Me? (Sally romance)

I went on the monkey bars and started to swing upside down form my legs. A girl then walked up to me as I jumped down from the monkey bars.

"Hi, I'm Sally!" she smiled. "Hi Sally, I'm Jett..." I said, shaking her hand. "How old are you?" she asked. "4, what about you?" I smiled at her. "I'm 4 too!" she smiled. She had curly brown hair up to her shoulders, and wonderful green eyes. She wore a pretty yellow sun dress along with black Mary Jane's.

"Want to play a little bit?" I smiled. "Sure!" Sally smiled back at me.

Jett had met Sally when she and him were both 4. After they had played, they had lost all contact with each other. But after years, Sally was dead. Jett didn't know this though... When he finally turns 10, Sally comes to his house to kill his family and him.

But she recognized Jett from somewhere. What could happen with all of this weird confusion?
