Difficult to understand foreign cultures, in case of Russian

Sometimes, I think I never understand other country's culture.

Why? How? What?

Of course, I am Japanese, one of mysterious, dubious, weird, exotic, eccentric, etc., etc. nations.

But, even though I'm such a ??? nations, races, still world is mysterious....(・o・)

Well, what is this?

They are Russian high-school girls.

How do you think?

You think Japanese style costume play (cos-play)?

Boooooooooooooo....(・o・)
