When we as writers see a blank white page, sometimes our minds go pitch black, and we're in danger of being "eaten by a grue." What's a grue, anyway? That being that lurks in the darkness and consumes us could be anything, really. By allowing ourselves to dance in the world of metaphor, we can begin to find our way in unfamiliar territory and tell a story that is relevant to the current situation, draws upon common understanding, and enlightens people with new perspectives at the same time. This is as valuable in technical writing as it is in fiction and screen writing.
