I still remember a science teacher telling our grade 8 class about the bugs that are always on us. By the time she was finished I don’t think anyone, even the most jocky types, were not squirming in their own skin.
Write about the creatures living on your head, those microscopic little things you can’t shampoo out but still try to. What kind of life do they have? Do they like the way your favourite hair conditioner smells? Did they lose a friend the last day you went out in the wind? What have they seen and done that you could wrap a story around?
