Vladimir Putin is in love
At least, that is what they say …
And that is where the West didn't get along with Russia or understand the Russian viewpoint.

There's a full U.S. TS/SCI clearance style relationship history in the article on Vladimir Putin.
There are a number of children desperate for fathers and whether they are his biological children or step-children, it's a point of honor more or less among men in Russia, with some single mothers altogether too quick to go straight to court on it.
Western European Protestant Christian men of the 19th century had to abjure that false honor and forfeit their invitations to dance halls and formal balls in order to keep their faith and avoid Russian presumptuousness. It wasn't considered reasonable that a formal dance routine fully clothed and no further intimacy than that would incur child support costs for the man, but he would have been deemed "responsible" for her the evening and night anyways to take her home safely.
It seems to be the case that people "danced" more 150–200 years ago instead of "dating" at restaurants and gaining weight as they do nowadays.
That chivalrous or chauvinist "honor" became an "honor among thieves" with Russian "thieves in law" operating in Europe and abiding by a "thieves' code" in those days. The "thieves' code" was an interpretation of civil law, and they were definitely in court with it. Occupations or lines of work were not once to be mentioned at such social gatherings: if a man made money and didn't "work" for it, he was considered an honorable thief in that society until Western European men felt the need to "prove their worth" with their skills and passion for the job and talk about what they did for work even off the job.
These are signs that the Kremlin as well as the White House with Trump's new ballroom may be opening up some more.
