Honestly, I think that every time a grown-up is labeled with the "acquired foreign accent", it's purely imaginary. There is a sufficiently broad variety of dialects across Russia to satisfy any "foreign accent" seeker . Not longer than a month or two ago, an old lady with a distinct western-siberian accent was marked down as a foreigner, absurdly enough. How is it that those who were raised in Ukraine and other "former republics" are the ones who are rock-solid on the idea of how a genuine Russian accent should sound? No offense intended, obviously.
