I think it is very important for people in the society to be given "two names".

When I send an email after a long time, I don't feel comfortable saying or being told something like "I've heard of you for some time"

I remember you. I do remember you, but when I want to tell you how I remember you, if I can use your "two names," it will be much smoother from there.

The Internet is littered with "Mr. Ebata, unloved by the English language.

"There is also "Mr. Ebata who jumped in (committed suicide).

It all comes back to "How to tell the difference between saury and mackerel".

I think the first "two names" are still correct.
