Recently, I got a mail that starts the phase "Ebata-sensei (Dr.Ebata)", but I feel odd.

I had resigned a lecturer of prep school, and I have never been a teacher.

No doctor degree and no professional specialist.

From the viewpoint of mail senders, I am afraid that it cannot be helped.

They think that "Ebata-san" might be too free, but "Ebata-sama" should be remoteness (Of course, everyone is stranger for the first time).

"Ebata-sensei" looks like to be good.

When I have made a lonely trip in China at twenty-one years old, I called old Chinese persons with "sensei".

As another way, “sensei" means "who is older than me".

So you call "Ebata-sensei", because "Ebata is born before me."

O.K. I can accept "Ebata-sensei".
