I took russian in college. I am miserable at foreign languages, (I also took a term of Hebrew, but cratered) and even now, conversation with a Russian 3 year old is beyond my capacity. But I think it was very useful. It was a huge education in the fact that other people really don't think the way we do. The grammar is different in so many ways, and the grammar enforces constructs that are the reverse of english. Russian requires double negatives, passive voice is not only acceptable, but required. In english, Passive voice seems rude. Russian like most languages keeps the thou form, and you use it incorrectly at your peril, while in english it vanished except for poetry in the time of Shakespeare. (I read somewhere that Korean has three second person conjugations, not just two, and you need to be very careful about all three of them) So I think Russian was very helpful to me. Even though I can't speak it at all. What is your experience?
