What I find similarly odd about bilingualism is that often I can't seem to translate one of the languages I speak into another. I don't have any problems expressing my thoughts in whatever form in either language, but converting already thought stuff from one language to the other is extremely hard. Maybe this stems from the way I learn languages (I've never been able to relate to the classroom-way of teaching; learned everything from talking to friends / reading prose in the foreign language - I don't think about which language to speak in, it just comes naturally, maybe best seen by the fact that I can dream in 3 languages, depending on what language I've spoken most on that particular day), so it might be hard to reproduce so you guys probably can't see what I'm saying, can you. :/
