“The world is full of apathy, but I don’t care” is a jocular one-line saying that has been printed on bumper stickers. “The world’s full of apathy, but I don’t care” has been cited in print since at least 1997 and is of unknown authorship. The saying has been included in many website lists of oxymoronic statements.
