Once I was traveling from north to south in a country of almost 6 to 7 hrs of journey by train which bring you out of the country in that time frame. Now the language will change also. As the train was in north of that country people were sitting quite and looking at sky or for that matter computer or just don’t know where. (In one country if you are in normal coach you can talk to anyone. If you are in sleeper coach to someone but if you are in first class AC you can talk to your self only as it is considered rude to ask what is your name where are you going and what is your income and how many children you have. People skip the question whether you are married or not as a rule only married people can have children. You can ask same questions in a general coach without fear and people will gladly share their all details real or imaginary just to make a impressions and speak very loudly to impress some girl if there is one sitting even 2 blocks away. May be she or her father hears that and selects you as her mate). In the middle of the country some people were talking. As the train approached the land of farmers the entire train was talking. The simple people were even in peasants dress. Singing dancing and enjoying loud talks are common in some parts of the world and laughing with open mouth is considered good. It’s a bad manner to laugh with full giggle or make loud sound or ask people about their personal details and its rude in some countries not to introduce yourself and get introduced. The rules and the manners change with civilizations. Man uses clothes to cover their body in civilized society he also wraps his ideas in mind not to be seen by anyone. Its cost of civilized society to have more psychiatric problems as man is social animal and to remain aloof can make him crazy. Can social behavior be related to richness of the person or nation or level of its development? Some nations are poor but rich in culture. Some have rich love stories to tell and some have population growing without love stories. Some don’t grow in population at all. What is the index of civilization and development and growth of an individual or a nation to have it or not to have it in mind? ,
