A writer friend: “I’ve suffered from too many books made boring in the name of realism to indulge it myself.”
Amen. If you have a trade-off between verisimilitude and cleverness, choose whichever will be the most fun. I’ll forgive hilarity but not tedium. Most of us are surrounded by boring people with incoherent, shallow thoughts all day long, and we don’t need to read about them too. Many of us are such people, however witty we may want or imagine ourselves to appear in our writing.
