When "normal" is shocking
(I don't understand why they call it "Defender of the Fatherland Day", given that Russians refer to their homeland as Rodina- the Motherland. But then, Russians do have a very quirky sense of humour...)
The closest equivalent in American understanding to such a holiday is probably "Veterans' Day". "Defender of the Fatherland Day" is the day on which Russians acknowledge the terrible sacrifices and hardships endured by their people during the Great Patriotic War (their name for WWII), and honour and exalt their military veterans.
That is as nothing compared to how they follow it up, though.
Honestly, out of about a dozen ladies in that photo, there was maybe one that was only slightly "tubby"- by American standards, anyway, by Russian standards she is likely regarded as a land whale- and they were all sitting around gossiping and applying each other's makeup.
In Japan and much of the Far East, for instance, there is White Day, which takes place one month after Valentine's Day on March 14th. But the nature of both days is actually reversed from the Western understanding.
On Valentine's Day in Japan, women give men small gifts, such as chocolate. (There is a rather amusing episode of the much-loved old anime series, Ah! My Goddess, that focuses around the comical results of Belldandy's unfamiliarity with Japanese customs like this one, much to Keiichi Morisato's embarrassment.)
And on White Day, on March 14th, men reciprocate by giving women small gifts.
These things happen in offices all over Japan and Korea. It is perfectly normal and traditional- indeed, if a man doesn't give at least some of the women in his office a gift, it is considered extremely rude and a significant violation of protocol.
But in the West, such simple gestures of appreciation and affection between men and women are the exception, not the norm, in professional environments.
