"no evaluative content": exactly. (Tried to highlight, but my highlighting is wonky today.) Didion can be very judgmental: Her fearlessness in saying what she thinks is part of her appeal for me and many others. But in this case, she's being descriptive rather than prescriptive, and that may help to explain why people like this quote. You don't have to worry that visitors will feel offended by your throw pillow, because it implies no judgment. Thanks for the perceptive comment.
