Here’s a great tip from Sid Fleischman:
Give weather reports. It helps the reality of a scene if foghorns are blowing or kites are in the sky on a windy afternoon or the day’s so hot wallpaper is peeling off the walls.
Why mention the weather? Boring?
Well . . . maybe you can do it in a fun, not-so-ordinary way, like the wallpaper peeling from the heat.
But most of all, it helps your reader get into your story. We can imagine . . . a fresh April day with little flowers just peeking out from the warm dirt . . . or a blustery November day with dry leaves skittling across the sidewalk.
Hey, that’s better than just any old day.
And maybe you can add an extra detail. Is that sidewalk cracked?
What does a spring day smell like?
As an Italian author once said, even in fantasy lands (like Narnia), it rains (or snows). If your characters need an umbrella or a heavy coat or lots of sunscreen . . . it helps us imagine that your story is real.
And that’s a good boost – to make your story just a little better!
