Another personal problem with my Japanese is that I only have been learning how to read and listen, not to speak or write it. But I mean, I see a lot of Japanese dudes, like Shigiru Miyamoto, that clearly understand English spoken to them, but still respond in Japanese (they have interpreters, but they only interpret the Japanese to English for the benefit of the English speakers). So I don't think it would be too rude of me to do the same if by some miracle I ever did get to go to Japan.
