I think it may be because it was his father's parents who said that. I read somewhere his mother's parents (or mother?) said Yuzuru's politeness was brought about by the decent education by his father.
It's nice to know that they are saying good things about their son/daugher in law.
I feel Yuzuru's character has been nurtured among those good people.
By the way, I learned Sota Yamamoto's SP this coming season is Poeta. This was one of the music pieces I wanted Yuzuru to skate
I love Lambiel's one, but I like Satoko's Poeta recently.

Oh, dear, there are so many, too many music types I want Yuzuru to choose :think:
