Russians
Russians do not use blinds at home, and curtains are rarely thick enough to block out direct sunlight.
Russian people are extremely hospitable, it is not for nothing that the statement about the breadth of the Russian soul is often mentioned in a speech, having established trusting friendly relations with a Russian person, you will be able to appreciate the friendliness and cordiality of the owner of the house.
The Russians superstitiously give each other only an odd number of flowers. An even number is appropriate only at a funeral.
For the Russian soul, there is nothing better than a holiday, and there can be any reason for celebration and noisy fun: be it a red day of the calendar or a colleague who unexpectedly appeared after a vacation.
