Okay.
Perhaps the Japanese people I've known, I've met mainly through school or career but those that I've interacted with, I have found to be quite well-spoken, if reserved, at times. When Naomi came on the scene she was very young and probably not all that sure of herself. I just regard her as a young woman finding herself and identity is inextricably linked to that process of growth. I guess I just tend to be sensitive to the declarations of surprise that someone being well-spoken as it often feels like an 'othering' of a person. I know you don't mean it that way. I've been on the receiving end of this compliment, only it did not feel like one.
In the West Indies it's common to encounter people who are both black and Asian, I have a few cousins and Aunts who are, the cross-currents of culture seems more common to me. The joys of being from an immigrant background, I guess.
