As the singer for the now-defunct New York screamo band Saetia once sang, “There is no happy here.” So where, exactly, is all of the happy? NPR correspondent Eric Weiner, author of The Geography of Bliss: One Grump’s Search for the Happiest Places in the World, knows that it’s out there somewhere—and he’s determined to find it. Weiner’s not so much interested in discovering the meaning of happiness as much as its simple location; he’s even gone to the trouble of developing his own “happiness scale,” with which he rates countries across the globe for would-be travelers. Iceland? A “quirky little nation” where the locals greet one another with a friendly “come happy.” Moldova? Well, not so much happy there. Weiner discusses and signs copies of his work at 7 p.m. at Politics and Prose, 5015 Connecticut Ave. NW. Free. (202) 364-1919.
