It’s important to avoid what science fiction writers sometimes call the “As you know, Bob,” paragraph, in which you do this big info dump. There’s pleasure in working it out. Besides, brief, understated descriptions tend to better serve the lens of character. Real people don’t think of things in quite so many adverbs, or adjectives. And then I like to think that withholding information also rewards readers who will go back and re-read the whole thing. All of those little enigmas play differently the second time through.
