Here are some other ideas:
- Track something. Use smell to lead you somewhere.
- Remember something. They say smell is the basis of our first memories, and the smell of my loved ones on pillows and jackets is something I absolutely use to console myself when they are gone. Where do familiar smells take you? What does the juxtaposition of, say, the smell of your grandfather's pipe in a new city cause you to think or feel?
- Look forward to (or dread) something. Whether it's the pre-Thanksgiving aromas emanating from the oven or the scent of lilies wafting in from the funeral parlor, those fragrances foreshadow things to come.
