It wasn't a slow process. One day you're making breakfast with your family, dancing around your kitchen, laughing at your dad's jokes. The next day, your dad isn't your dad and you've no choice but to end his life as the memories flood your mind. Choke back the tears as you raise the gun to his head. Close your eyes as you pull the trigger. Then leave his lifeless corpse, move on, forget what your life was before. It's A Walker's World now.
