Congressman Emanuel Cleaver of Missouri has an idea that deserves to pass Congress 535-0. Cleaver, a Democrat, is looking for co-sponsors of his resolution designating next Wednesday, the day before Thanksgiving, as “Complaint Free Wednesday.” In a letter to colleagues, Cleaver writes that everyone experiences occasional “anxiety, frustration, stress and regret,” which can give rise to bellyaching. “Complaining keeps people stuck on current problems, inhibiting them from thinking constructively to find solutions,” he writes. “Research has also shown that complaining can be harmful to one’s emotional and physical health; relationships; and can limit professional career success.” His resolution recognizes the group Complaint Free World, whose goal is to get 1 percent of the world’s population (about 60 million people) to be complaint free. A gimmick? Publicity stunt? Maybe — but you won’t hear us complaining about it.
