When describing nature, a writer should seize upon small details, arranging them so that the reader will see an image in his mind after he closes his eyes. For instance: you will capture the truth of a moonlit night if you'll write that a gleam like starlight shone from the pieces of a broken bottle, and then the dark, plump shadow of a dog or wolf appeared. You will bring life to nature only if you don't shrink from similes that liken its activities to those of humankind.", May 10, 1886)
Create a world in front of your readers where they can taste, smell, touch, hear, see, and move. Else they are likely going to move on to another book.

[Referring to passage by Alice Munro] Finally, the passage contradicts a form of bad advice often given young writers -- namely, that the job of the author is to show, not tell. Needless to say, many great novelists combine "dramatic" showing with long sections of the flat-out authorial narration that is, I guess, what is meant by telling. And the warning against telling leads to a confusion that causes novice writers to think that everything should be acted out -- don't tell us a character is happy, show us how she screams "yay" and jumps up and down for joy -- when in fact the responsibility of showing should be assumed by the energetic and specific use of language.
Now the second common characteristic of fiction follows from this, and it is that fiction is presented in such a way that the reader has the sense that it is unfolding around him. This doesn't mean he has to identify himself with the character or feel compassion for the character or anything like that. It just means that fiction has to be largely presented rather than reported. Another way to say it is that though fiction is a narrative art, it relies heavily on the element of drama.
