Russia is a great country. Before an alien can visit it, he needs to know some things about Russia.
When the Russians meet shaking hands, and if they are very familiar, they can also embrace.
When you go to someone in the house or apartment at the doorstep, take off your shoes.
Unfortunately, Russia is not a very smiling country, so everyone will not be able to smile at anyone who walks about.
Arriving in Russia, you should know a couple of very tasty, national dishes: borscht, dumplings and very tasty pickled cucumbers.
If a person is close to you when talking, we are so accepted.
