You sit covered in germs. At every opening they sit and wait, waiting for the moment you're at your weakest, when they can make their attack. Either side of your mouth is a warty growth. At your nostrils sit endless soldiers, in spite of everything you put out to remove them. Each crevice and crack pullulates with them, growing and feeding, splitting off from themselves to spew out more. These villains will rape and ravage you for their own benefit, never realising that the day their happy host perspires will be the day they sign their own death warrant.
You are Earth. They are Humans.
