It was great to see my long-time friend Prof. Harumasa Sato and his family in Kobe and introduce Kai (I say long-time friend, because I don’t like using the word old after 40).  We got to see the new faculty building in Nishinomiya — so modern and clean that it makes all the places I’ve studied in look like tenaments.  We enjoyed a pleasant Japanese meal together, and Kai treated us by sleeping through 90%.
