In general, Germans are very friendly to all nationalities, Russia is not an exception. The only thing that bothers me here is a certain social isolation…perhaps it is not only peculiar to Germany, but to all EU countries.
In Germany home and family are the most important things: friends, neighbours, colleagues and other acquaintances (especially after marriage 🙂 ) remain in the background. So the holidays are usually carried out only in the family circle…. forget about a good company of a close friend without an invitation!!! It took me a while to get used to it, but now I enjoy the fact that my German husband always comes home on time and pays attention to me and our children, no chit chat with friends or colleagues in pubs 😉
