Explain Why Show Don't Tell Actually Works

You have heard show don't tell in every piece of feedback you have ever received and still could not define it if asked. This explains the difference using one plain example, nervousness before a job interview, so you can see exactly what changes on the page. For new fiction writers tired of nodding along to advice they do not fully understand.

I keep being told to 'show, don't tell' in feedback on my fiction, but nobody explains what that actually means in practice. Using a plain example (a character who is nervous before a job interview), explain the difference between telling and showing in concrete terms: what changes on the page, why showing creates a stronger reader response, and the situations where telling is actually the right choice. Keep it to plain language, no writing-workshop jargon.
