I take German classes and have been learning for about 5 or 6 years, I’d have to give German up, which isn’t a problem as I don’t really feel the need to continue.
I already speak a little bit of Filipino, Japanese and I can say a few things in French. (Not much though. And I’m Scottish, so it sounds really funny when I’m speaking French.)
I heard Mandarin is a hard language, but I love Asian languages 🙂
