probably the best irl example of "show dont tell" is when you go through the video progress bar on a song on youtube and on the start of the song it says "most replayed"
Another way to think of show don’t tell is to describe the symptoms rather than tell the affliction. You could say someone was close to fainting—or you could describe their symptoms and trust the readers to understand what they mean: the world swirled around her head, her ears beginning to hum lowly, then louder, increasing into a high-pitched ring. She took a deep breath, her stomach turning over itself. Etc.
Symptoms can also mean the lump in your throat as a “symptom” of being sad enough to cry, or the warmth of your face as a “symptom” of embarrassment.
That might sound a bit silly, but I find it really helpful when I’m reading over mine or others work and looking for those places where showing would be better than telling. Have you described the symptoms, or just told the affliction?
Here’s a short list of “afflictions” and their associated “symptoms” to get you started (but make sure to explore how different characters express different afflictions, even in more odd or unusual ways!)
Any symptoms I missed?
One thing I’ve learned about writing is ”give everything a face”. It’s no good to write passively that the nobility fled the city or that the toxic marshes were poisoning the animals beyond any ability to function. Make a protagonist see how a desperate woman in torn silks climbs onto a carriage and speeds off, or a two-headed deer wanders right into the camp and into the fire. Don’t just have an ambiguous flock of all-controlling oligarchy, name one or two representatives of it, and illustrate just how vile and greedy they are as people.
it’s bad to have characters who serve no purpose in the story, but giving something a face is a perfectly valid purpose.
