The person I am when speaking Japanese is quite quite different from the person I am when speaking English.

That's interesting, Bridget. Do you mean that you sort of
mentally adopt their cultural mannerisms as well? I have little knowledge of their culture, so this may not be a good example, but I believe they place a high value on respect, so using that, when you're speaking Japanese would you be extra-careful to ensure that your speech (and mannerisms?) demonstrated respect?

I am delighted that you're posting again, Dearest!
