It's a big big leap over learning something like French. Everybody thinks the Canadians are bilingual but the fact is there's only a little mandatory French education in the schools and then you either keep taking it or choose not to. I have a friend who did keep taking it and after eight years of classes he knows how to order a lunch and ask people for directions. He can't have conversations.
I can relate to this. Prior to visiting Europe, I actually took a few French classes so that I would not have much difficulty asking some basic questions. While the vocabulary and pronounciation is not difficult, it is a completely different story when you are in a conversation with a fluent speaker. While I could understand sentences when they were right in front of me, I could barely understand anything spoken to me while in France; they spoke much too fast for me to be able to pick out individual words.
