Today, I went to Kyusyu university for the meeting with prof.Yamaguchi.
I was very relieved when I discussed with prof.Yamaguchi because he understood and respected my study.
It is very important thing.

By the way, yesterday was very happy day.
My third son, he is 10 month baby yet, could stand by himself!
It was just one time, but I surely saw it!
He placed his hand on the first and second steps of the stairway in my house.
And stood!


My first son saw it too.


My wife was taking the bath. 
And my second son was at the first floor.   


Therefore, I and my first son were just persons seen it.


We felt very happy!
