I think I would jump at the chance to learn any language I don't know -- which is most of them!

Well, except maybe Spanish ... I guess I find it boring. Dunno why. I could probably get use out of that one living in the US.
I've always been interested in eclectic things, and language is no exception. The only 'normal' language I've learned is French. Of the languages I know (aside from my native tongue, English), my best is Klingon. I love it because it's so different from English, and probably because I'm a Star Trek fan. My Latin is busy rusting away to nothing, which is bad. I need to remedy that. Oh, yeah, and I have some materials for learning Lenape, the language of the Lenni-Lenape Indians (also known as the Delware Indians), who used to live in these parts. Haven't got too far with that just yet.
If I had to pick a few languages to learn, I'd probably choose Russian, maybe Swahili, Polish for sure (I'm part Polish -- I have this vague memory of my grandmother singing me a song in Polish -- something about an apple tree...). I'm interested in Japanese as well. So many languages, so little time! (So little brain power/space!)
I've just signed on as a translator of English into Klingon, so if you need anything, let me know!
