Today it was pointed out to me that it was obvious by the way I compose my project request forms that my politeness level was still pretty much tuned to the Japanese standard. The request started, "Could you please...". Didn't find that at all odd myself, but who knows. I'm still not quite completely tuned into the channel here, if you know what I mean. Still, I think polite as a default mode for human interaction is not a bad thing.
I spent twelve years of my life in Japan. Intentionally (for the most part). A lot of things permeate in that length of time. I knew when I left here that if/when I came back I'd be different. That was kind of the point.
