"The motherland of Russia.

Disclaimer: Note that some of these bullet points are just generalizations based on my experience living here as a foreigner for 6 years. Some locals do/don't follow the rules, but the Russians know they are generally accurate.

1.) Handshake by the door entrance: Never shake a person's hand before entering the doorstep as doing so is cursing the house owner. Don't do it.

2.) Whistling in the public/or anywhere: By doing such a casual gesture immediately identifies you as a non-local. This is because the Russians believe that by whistling you're blowing your wealth away.

3.) Similar to many European countries, you stand on the right lane of the escalator by default. The left lane is reserved for those who are in a hurry. So don't be that idiot that stands in the middle of an escalator, people in big cities like Moscow don't tolerate that very well from my experience. Which leads me to the next point.

4.) Not knowing when to show aggression. The Russians are known to be direct and confrontational, they are not afraid to show their fangs when feel threatened. So if you're the timid little guy who grew up in Asia and tend to swallow up things, there you are~non local.

5.) Not saying приятного аппетита всем(Priatnava Appetita) as you enter a room full of people eating. It's a polite gesture of wishing people to enjoy their meal, some of you know it better as Bon Appetit. Not saying it doesn't make you a non-local, but by saying it certainly shows you have lived in this land for some years.

6.) Not saying будьте здоровы(boot-eh zdarovi). You say that when someone sneezes, it means bless you! Similar to above, saying this to a Russian when he/she sneezes, they'll embrace you better as part of the российский (rassiski) family.(note I didn't use the word русский(ruski) because this term is reserved for Russians by blood.)

7.) Two is better than one? Not necessarily so in the Russian culture. Buying flowers for the girl you're in love with in even number is as good as wishing her dead. Don't believe me? Try it on your own ;)"
