Laura: Harold is obviously lonely. He should sell his cabin in the woods and move into town. In town he will be near other people all the time, so he will not be lonely anymore. Ralph: Many very lonely people live in towns. What is needed to avoid loneliness is not only the proximity of other people but also genuine interaction with them. Ralph responds to Laura by pointing out that ['what is appropriate in one case is not necessarily appropriate in all cases', 'what is logically certain is not always intuitively obvious', 'something needed for a certain result does not necessarily guarantee that result', 'various alternative solutions are possible for a single problem']
