Prospective -- or actual -- writers are always given the advice, 'show, don't tell.' It's considered to be more engaging as a storytelling technique to let your reader know what's happening by letting them experience it via the experiences of your characters, rather than merely informing them what happens to your characters.

Good enough advice, in general. But there are always counterexamples.

This morning on the way to work I read a story on Tor’s website, which is almost entirely telling; and almost entirely wonderful.

Six Months, Three Days’, by Charlie Jane Anders. Highly recommended.
