Show, don't tell is the most repeated advice in writing, and also the most misunderstood. Telling is not always wrong; sometimes a sentence of summary is exactly right. The problem is telling when the reader should feel something. 'She was nervous' tells us a label, while 'She checked the lock three times before she could make herself leave' lets us experience the nervousness ourselves. Showing gives evidence; telling gives a verdict. Readers trust evidence more.

Consider emotion. Telling: 'John was angry at his boss.' Showing: 'John read the email twice, then closed his laptop so hard the coffee jumped.' The second version is longer, but it earns the emotion instead of announcing it, and it reveals character: John controls himself, but barely. The trick is to translate an abstract feeling into a concrete behaviour, a physical detail, or a line of dialogue that implies the feeling without naming it.

Setting works the same way. Telling: 'The town was poor.' Showing: 'The laundromat's dryers ate quarters and gave back damp clothes, and the hardware store had been a hardware store for so long that its sign had faded to a ghost.' The details do double work: they establish poverty and they create atmosphere, while the telling version gives only information. Choose details that are specific and slightly surprising; generic details, like peeling paint, feel like telling in disguise.

Character works through action and choice. Telling: 'Mara was generous.' Showing: 'Mara tipped the delivery driver with the last twenty in her wallet, then walked home in the rain because the bus fare was gone.' A character's choices under pressure reveal them more honestly than any narrator's summary. When you catch yourself writing 'he was kind' or 'she was brave,' stop and invent a small scene where the character proves it, even if the scene is only two sentences long.

Knowing when to tell is equally important. Tell when the information is routine, when a transition needs speed, or when the emotional weight is low: 'They drove to Chicago on Tuesday' does not need a scene. The rule of thumb is to show the moments that change your character or carry emotional weight, and tell everything else. Writers who try to show everything produce bloated drafts; writers who tell everything produce flat ones. The art is choosing which moments deserve the full scene.

A practical revision exercise makes this concrete. Take a page of your draft and highlight every emotion word: sad, angry, happy, afraid. For each one, try replacing it with a behaviour, a sensory detail, or a line of dialogue. Keep the replacements that make the passage stronger and revert the ones that made it clumsy. After a few rounds, the habit becomes automatic, and your prose gains the texture that separates competent writing from writing readers remember.

Dialogue can show what narration only tells. Instead of writing 'He was a boastful man,' let him say, 'I closed that deal before lunch, and frankly, the client should thank me.' The reader hears the boastfulness directly and forms their own judgement, which is more convincing than the narrator's label. Similarly, a character who apologises three times in one conversation shows insecurity without anyone naming it. When revising, look for places where narration labels a trait and ask whether a line of dialogue could demonstrate it instead.

A useful test for showing is the camera test: could a film camera capture what you wrote? A camera can show a trembling hand, a slammed door, or a character turning away, but it cannot show 'sadness' or 'regret' as abstract labels. If your sentence fails the camera test, rewrite it as something visible, audible, or physical. Interior states still belong in fiction, but they land hardest when they follow observable evidence, letting the reader feel the emotion before the narrator names it.
