Before I published my first novel, I wrote stories for fun and posted them on a fanfic website. Many of these early stories took place in winter. Why winter? Because I'm Canadian and I live in the north. I have four seasons: Spring (lasts 1 month), Summer (lasts 3 months), Fall (last 2 months), and Winter (last 6 months). So, I spend half the year in the snow and the cold.
In one of these fun stories, my character was forced to drive in a snowstorm without winter tires. Needless to say, he ended up in a ditch. After reading that story, a reader sent me a message asking me what were winter tires, and why we didn't put 'normal' tires on our cars in Canada. I told her that winter tires look like 'normal' tires but they have a higher natural rubber content to keep them supple in cold weather and deeper & thicker treads, allowing for better grip and handling on snow and ice.
She lived in a part of the world where it's always warm, so she didn't understand how snow, ice, and cold could affect our lives differently. It was the start of a long conversation about car accessories: winter tires, studs, chains, winter wipers, block heaters, battery blankets... then houses: triple windows, insulated attics, basements, furnaces...
Looking back, I learned a lot from the exchange. I realized just because I knew about certain things didn't mean everyone else did. Sentences like "it's cold out" or "there are northern lights in the sky" doesn't mean anything to someone who'd never felt cold or seen northern lights.
As a result, I learned to become more descriptive, to look at a scene through my characters' eyes as if they were seeing it for the first time, and to assume that at least one of my readers will never have experienced what my characters see, hear, feel, sense, or smell.
Happy Reading & Stay Safe! J.S.
