You know, six pages and I still have no idea what you are all on about. At the start it seemed to be about some guy named Ken's hat, and now your going on about how someone you lives in Japan needs to have PERFECT English?
The way someone writes, or what language they speak in shouldn't matter. Humans all have the same type of vocal system. It isn't the language, it's the message. I hate people that don't use correct grammar and pronunciation, unless they have a good excuse. And she does. And it's pretty good.
One of the subjects we have to do this year is Japanese. And I suck at it. It's impossible. So it's still pretty good that someone can learn a completely different language, with a different alphabet and sentence structure, even if they miss a few capitals or commas.
Now, back to the pressing and life saving topic of Ken's hat?
