Etiquette is a very important thing in society. It allows people to hear themselves, make the world safer, and generally makes life more beautiful and simple. Each sphere of life has its own etiquette rules: for example, in the subway cars, first people leave and then they stop; need to give way to pregnant women and people with young children; It’s worth taking backpacks off the back, because they cause problems standing nearby. These rules are not officially fixed anywhere, like all etiquette rules, but everyone knows them and thanks to them, people feel more comfortable in public transport. Etiquette forms an amiable relationship between people and testifies to human mutual respect.

Public places also have their own rules of ethics. For example, in the theater you can’t make loud noises, eat, interfere with listening, sit in outer clothing. In cinemas, you need to be late, quietly go to your place. In stores, you must adhere to the line, do not scream and behave calmly. Of course, there are people who ignore these rules. In my opinion, such people are ill-mannered, theirs was similar in the family. Indeed, often our behavior is copied from the behavior of our relatives, parents, and our inner circle. Also, these people are rude and ignorant, selfish, who do not see anyone else's needs except their own.

Etiquette is also designed to help people. You can often see how the weak help the strong, and the younger - the older. This behavior indicates that all of us people live as one family in one country, we must live in peace, and not to promote violence and aggression.
