i want to learn more than i know

English is my native language, but I was in a French Immersion School as a kid, so some of my basic instincts are to say things in French (counting, for example. I used to do it partially to show off, but it's really mostly instinctual). I want to get back into it, though. I took Spanish for 4 years and got a 4 on the AP Test, but I wouldn't consider myself fluent. I can talk slowly and comprehend basic things. My on-the-fly responses are often grammatically incorrect. I really want to learn the language of the Tribe(TM) because if it has vowels, I can read it, write it, speak it and even sing it, but I have no idea what I'm saying! I also want to learn my grandfather's dialect, because it's a dying language and less than 500 people speak it. Sadly, I don't think I'll be able to learn it in time.
