Causes of the problem​

Courtesy этикет courtesy is a set of good manners which we use in everyday life. good manners and rules of behavior at home, work, transport or other places, are very important in modern society. even in ancient times people had to observe certain rules of conduct, which made their lives easier. a person is seen and evaluated through his behavior and communication with other people. if someone has a rich and beautiful inner world he or she demonstrates high level of social etiquette. sometimes when we simply say “hello! ” meeting people and “good bye! ” leaving, it shows our good manners. it is also necessary to use polite words in formal situations and when talking to strangers or elderly people. for men it is a good manner to let women go first. most people hold doors for the next visitor in stores, restaurants and other public places. young people ought to give place to older and disabled people in public transport. pregnant women and little children also have a priority in such situations. table manners are another important issue. while at formal dinners, people usually eat with fork and knife. soon after sitting down at the table it is correct to put a napkin on your lap. well-mannered people usually know the rules of table setting. when there is a variety of silverware in front of you, it’s a good idea to start with the knife, fork or spoon that is farthest from your plate. not everyone knows the rules of courtesy. there are also many people who have bad manners. for example, they talk or laugh loudly in public places, which is not acceptable. they litter in the streets or cause inconvenience to other people. they stare at people they don’t know and never say “sorry! ” or “thank you! ” such behavior should be avoided if we want to be a part of civilized society.
