That is really cool! In first year I was thinking about taking linguistics just for fun, as an elective (languages are awesome) but there ended up being too many music courses I wanted to take...which all turned out to be a giant waste of time, lol. A friend of mine went to teach English in China for a semester the other year, and she loved it, even though she could barely speak Chinese - it seems like a really fun, rewarding thing to do. How much Japanese do you speak? One day, after I've got around to mastering German, I will for sure make a start on Japanese, it is a mad awesome language :D
