Actually, if you think about it, abusive swearing is not just unethical. It is also an expression of contempt for the opinions of others. So why not swear?
It is known that language can be used to Express emotions (in the case of failures, conflicts and so on) and a bunch of words. In the second case, swear words are often "patch the gap" in vocabulary. If it is poor, there are "well", "shorter", and if the person is still rude and some language. People are so accustomed to the Mat, that it becomes a bad habit, get rid of that is no easier than, for example, to quit drinking or Smoking.
If the person without the Mat can not, it means that he has any complexes, he simply can not properly build his speech. But some swear so brilliantly, that it seems as if the art of man perfected all his life. But in any case to listen to foul-mouthed unpleasant.
Especially need to pay attention to his speech to the people, who have small children. Kids easy, literally on the fly catch every word, repeating mom and dad. So watch what you say. Even if you accidentally hit the hammer on the toe or slipped and fell, not the mother.
Think in advance, what can you say in such cases. Because the Mat is very easy to replace on interjections, in the Russian language which abound. Watch not only for lack of speech, swear words, and purity of the language as a whole. Let there be words-parasites, a variety of jargon. Make it a strict rule.
But if the child is "brought" a bad word from kindergarten or school, will need to talk to him, firmly but gently enough. Explain to your child that foul language is ugly. Give examples of when the swear words and expression let people down, put them in an unpleasant situation.
There are cases when the child hears somewhere a dirty word and asks the parents to explain its meaning. Tell us what is a word only bad people who want to offend anyone. If you explain it gently and correctly, then most likely, your children will not want to use to communicate with you and with peers of words that does not serve as an ornament of the great Russian language.
