I would like to be fluent in Thai, Northern Thai (which is really more of a seperate language than a dialect--it is to Thai as Portugese is to Spanish), and Lao. I love that particular corner of the world, and really enjoy the sounds of those languages and the look of the script. I have a lesser desire to learn Spanish, French, Italian, Hausa, Swahili, Hindi and Arabic.
I find written Korean fascinating, and would love to learn to read it, which I suppose would involve my learning to speak the language as well.
