What other foreign languages do you know? Which one(s) do you want to learn?
Spanish, on which I could survive if I had to but it wouldn't be pretty. Japanese, I think I hit kindergarten level on my DS coach and have forgotten to play it ever since verb rules confused hell out of me. German, uh, a very very little.
I wish I could trade my Spanish knowledge for its equivalent in Japanese, and my barely-there Japanese for slightly-better German.
