Passage Four
Ideasabout polite behaviour differ from one culture to another.Some societies,such asAmerica and Australia,for example,are mobile and veryopen.People here change jobs and move house quiteoften.As a m result,they have a lot of relationships that often last only mashort time,and they need to get to know people quickly.So it′s normal to havefriendly conversations with people that they have just met,and you can talk aboutthings that other cultures would regard as personal.
On the other hand,there are more crowded and less mobile societies where long-termrelationships are more important.A Malaysian or Mexican business person,for example,willwant to get to know you very well before he or she feels happy to startbusiness.But when you do get to know each other,the relationship becomes muchdeeper than it would in a mobile society.
To Americans,both Europeans and Asians seem cool and formal atfirst.On the other hand,as a passenger from a less mobile society puts it,it′s no fun spending several hours next to a stranger who wants to tell you allabout his or her life and asks you all sorts of questions that you don′t want to answer.
Cross-cultural differences aren′t just a problem for travelers,but also for people in daily life.Some societies have"universalist′′cultures.These societies strongly respect rules,and they treat every personand situation in basically the same way."Particularist"(强调特性的)societies also have rules,but they are less important than thesociety′s unwritten ideas about what is right or wrong for a particularsituation or a particular person.So the normal rules are changed to fit theneeds of the situation or the importance of the person.
