Zombie Apocalypse

I decided to stay home and study a bit and eat breakfast. My mother asks me to rake the lawn. Okay. I hate to rake the lawn, as my neighbors always try to converse with me. But okay. My backyard isn't fenced in. I begin to rake and see someone out of the corner of my eye. No doubt an elderly neighbor working on their garden. It is indeed, but she's too close for comfort. I shift myself, but she continues to grow closer. I decide to initiate conversation to break the tension, but when I see her face, she looks disgusting. Her face is bloody with multiple of what appear to be bite marks. And she's... growling. At me, no less. I try to elicit any sort of response from her, but by all accounts she's... dead to the world. My mother lets my dog into the backyard and he runs up to the neighbor, happy to see a new person. I put my foot out, so that he cannot come in contact with her. Horrifyingly, she aims a bite at my leg. Out of instinct, I swing... And knock her head off. I scream, taken aback by my own strength, my dog is evidently not perturbed by this sequence of events and begins to lick her beheaded body. "Get away from that!" I lunge for my dog and carry him inside. I tell my mother what happened, and she attempts to call the police. While she waits, I notice the neighbor took a bite out of my leg.
I die eventually.
