How extraordinarily different, again, are the attitudes of different people to their fellow men! One man, in the course of a long train journey, will fail entirely to observe any of his fellow travelers, while another will have summed them all up, analyzed their characters, made a shrewd guess at their circumstances, and perhaps even ascertained the most secret histories of several of them. People differ just as much in what they feel toward others as in what they ascertain about them. Some men find almost everybody boring; others quickly and easily develop a friendly feeling toward those with whom they are brought in contact, unless there is some definite reason for feeling otherwise. Take again such a matter as travel; some men will travel through many countries, going always to the best hotels, eating exactly the same food as they would eat at home, meeting the same idle rich whom they would meet at home, conversing on the same topics upon which they converse at their own dinner table. When they return, their only feeling is one of relief at having done with the boredom of expensive locomotion. Other men, wherever they go, see what is characteristic, make the acquaintance of other people who typify the locality, eat the food of the country, learn its manner and its language, and come home with a new stock of pleasant thoughts for winter evenings. Which statement best express the main idea?
