Zombie Apocalypse

So basically you are with you're friend Lilly, (Ur a guy) yall are sitting at a park when dark clouds begin to appear, the area seems devoid of all life, you are joking around talking about how its like the beginning to a horror movie, or how its like a zombie apocalypse is about to start when suddenly you see one, out in the distance. You think its just a tweaker because its pretty common but you see it bite another person thats when reality sets in(Shes 14 so r u)
