Super professional eye contact = you can reenact things you saw

One day, Mr.Mukoyama was asked by an educational trainee after the class that the trainee showed.
The trainee said to Mr.Mukoyama "Please tell me something about my class lesson."
The answer that Mr.Mukoyama gave him was below.

"I would like to tell you just one thing." I said. Then I recalled the class lesson. "While you had the students do math practices, you were moving around the classroom, weren't you?  What did you try to look at that time?" ... "And furthermore, you are wrong." ... I drew the figure of the classroom and explained that all respective students made what kind of mistakes specifically.

The point is that he said "I would like to tell you just one thing" and then he "recalled the class lesson".
