I am married to a beautiful russian girl. That I like.
In my experience there are some pro's and cons with russians (as with others).
When you get a russian friend, he or she is often a truly good friend that is there for you all the time and will go far to help if needed. Russians are friendly, they share whatever they have if poor and they are fun to drink with.
What I don't like about russians is the constant focus on money! In everything they do or talk about, there is always a money issue! And the fact that it seems to me that the russians who have some (or much) money, just HAVE to show everyone this! It looks like the most important thing is to have more and better stuff than your neighbour and friends. I just hate that, because believet it or not, I am not in love with money! So, if I was doing business i Russia, well.... I would be carefull! Just google for "telenor+russia" and read.
But, overall - normal russians, ukrainians and belarussians are fantastic people! ANd the girls are HOT!
