Forget all the guff about living overseas and how it broadens a person's horizon. Living in Japan is a series of frustrating reminders of how much better things are run, done or organised in other countries - except England of course.

I speak enough Japanese to get by and have some very good Japanese friends and really enjoy living here (in the winter), but I've definitely become more bigated since leaving Oz.
