Late this past summer, I officially became a "half."
No, not a "half" in the sense the Japanese use the word, that being for children of international marriages. (In other words, those kids who are half Japanese.) Rather, I have become a "half" time-wise. For more than 50 percent of my life has now been spent in Japan.
I have never been too keen on the first usage of "half," as from certain perspectives it implies something less than whole.
