There is also a clear separation between sex and family. People marry young in Moscow, typically between the ages of 18 and 24. I imagine it s even younger in the provinces. And then they start affairs. What is interesting is that the affairs are not too clandestine and there is never any feeling of remorse attached.
Women cheat on their husbands quite a bit as well.
In all my years of working in the US, only once did I know of an office romance. Here it borders on ridiculous. In our organization, I have a feeling that all single people have gone through all possible boy-girl permutations. I am also aware of two married men who are cheating on their wives with girls who work in the office. Trust No One Pathological liars.
