When I sorted the ads for recruiting for "English conversation lesson" for circulation boards of the neighborhood association,
My wife asked me "Do you want to start an English conversation lesson ?" in a black rage.
"It might be highest possible misunderstanding in several years"
I almost burst into laughing.

One day on Sunday, when I worked at hall counter,
a foreigner at the next town came to the counter to try to reserve a room for the event of "English conversation lesson".
As just a trigger, I started to help her for inquiries to the head of the neighborhood association and ads distributions by the circulation boards, by e-mail.

I am a writer of the works whose title is "New strategies for engineers who are not loved by English". So even if I try to start "English conversation lesson" by myself,
this is not a "joke" but a "serious affair"
