I feel ya on that last comment. Eventually I will say something without crazy errors in public... eventually.
Ha! Yeah, I've given up. As long as I can make myself understood, I'm happy. Speaking without errors in public is a dream at this point...
Just out of curiosity... When you, or someone else is speaking in your comic, is it in Japanese (that you translated into English), or are they speaking in English, in which case your elementary school kids do amazingly well.
You can safely assume that everything is in Japanese unless two "foreigners" are speaking to each other. Also, my elementary school kids do use English when they're in the classroom, but when we're eating lunch we're usually speaking Japanese.
