I used to sing in Greek, which I learned from my Greek roommate's friends at Stanford and later working in San Francisco. They said I could speak it without an accent, which I think was because of the shape of the teeth or mouth. I could not pronounce German and gave up. I learned enough French to pass the Master's Exam in reading it (learned it with two quarters in class and reading the Montreal newspaper). but I could not
pronounce it well, so it was a strain when trying to do French in French cafes. So the only language I learned pretty well was Greek, but that's so long ago that I could not even read it now.
My best friend of my young years had a daughter who got a Ph.D> in Russian and ended up a translator in Washington D.C. She was very pretty and looked a little like I see pictures of the Romanov girls, but she was Danish rather than Russian. she married a Drama professor who was said to be of gypsy extraction.
