“Snakes… Why did it have to be snakes….???”
What a character likes and dislikes takes the curse of its larger than life stature. Whether you are writing a novel, play, screenplay, or teleplay, your characters loom in the hearts and minds of the audience. No one can relate to a loom. To humanize your characters and bring them down to size, give them feelings rather than just points of view.
You work in an office. Everyone does their job. The place runs like clockwork. Who ARE these people?! Until you know if they love football but hate sushi, you don’t really know them all. Who CARES what their functions are; more important to your readers is what do they take in their coffee, or tea, or do they not touch either but guzzle cola and pistachios.
Red. Does it do anything for them? What about wall paper patterns with thousands of little ducks? The things your characters like and don’t like set them apart from the crowd. And letting yourself go a little bit off the wall can bring forth attractions and repulsions that can suggest settings for a whole scene, sequence, or even the whole story itself.
Work yourself into the words. If you have pet likes and dislikes, this is the place to spout off about them. Assign them to your characters and you can get back at all those hated things, and express all those yearnings for the loved ones.
