Laura Lippman, I'd Know You Anywhere
That seems like good advice for writers, yet when I read the short passage above from Laura Lippman's novel I'd Know You Anywhere, the two words that jump out at me are "generically kind," an adverb and an adjective. It would take a lot of nouns and verbs to create the image Lippman creates with those two descriptive words.
You need not attend church to know the kind of people Lippman writes about. These are the people who shake your hand without actually looking at your face. They say, "We're glad you could be with us this morning," without giving any evidence they mean it or will remember your name if you return next Sunday. We find generically kind people working in restaurants and shops all the time. They say their polite words and phrases as if they have memorized a script, giving no indication of sincerity.
What Lippman calls generic kindness beats no kindness at all, and is certainly better than rudeness. Yet unlike the character in her novel, most of us would probably prefer a bit more genuine kindness in our daily lives.
