English is my primary language and although Canada has been officially by lingual for a long time I know very little French. I can however swear in at least half a dozen different languages being lucky enough to grow up in a multi ethnic community. I also can get by in speaking German but the reading and writing of it is not there.

I think OZ is exactly right in that you know a language when you think in it before speaking rather than translating it in your mind first. That happens to me when I spend more than 2 weeks in Germany on a visit.

Unfortunately at this point in my life I have zero desire to learn another language.
