Remember a time when you thought you had lost something. How much energy you spent looking depended upon how important the item was as well as how soon you needed it.
If you were packing for a trip and couldn’t find the documents for your presentation, you probably put a considerable amount of time into locating them. If, however, you had misplaced your comb, you most likely terminated the search and bought a new one.
What if it was an anniversary card for your best friend? A Father’s Day card for your loved one? Or the key to your house that you intend to give to your house sitter? Perhaps it’s the blouse that matches the slacks you’re wearing for a special night out?
Or, if you’re extremely unlucky, you feel as if you’ve lost a piece of your mind.
Your character probably has lost a thing or two. How does that play out in a story? If the item is a priceless heirloom, she might try to track down the last person who touched it.
If the object turned up missing after a burglary, your character might feel both bereft and violated.
If it’s his mind, his memory, he might go through periods of bereavement followed by periods of blankness.
Your task is to write a scene in which something is missing. Your character reacts to the loss in the way only she would. Narrative and dialogue are important. Description of the object, the emotions, and the search are critical.
Have fun with this one.
