I read Chaucer in Russian as a teenager, got disgusted with cheating skanks, and never bothered reading it in English even when my English became fluent. But my English is about as fluent as linguistically untalented person's can be. Heck, I bloody well think in English most of the time (then translate into russian when posting here). And I'm equally unable to say the "seashells" tongue-twister in English and "Sasha po shosse" in Russian :)
