Idlers are often spontaneous, relaxed, and untroubled: In this sense, careless is synonymous with "carefree," meaning free of sadness. The other sense of the term - being negligent or derelict in one's duties - may apply to the slacker, but an idler's duty is poiesis, creation of himself and his world. In this, he is never careless. See: DETACHED, DODGER, INSOUCIANT.
