Everywhere I go these days I either smell gingerbread or eggnog. Don't get me wrong, I LOVE these smells, and in fact, these smells are probably part of what makes me love this time of year so much.
With that in mind, think of your characters' favorite smells. What are they? How often do they get a chance to smell these favorite smells? Do these smells stir up any special memories for your characters?
How can you introduce one of these favorite smells for one of your characters today? What is his or her reaction? Can you pull up a memory of either the last time he or she smelled this smell or the first time?
