        Well....who can blame a young Akane?  :)  I think she would be
referring to Tofu, the person, instead of Tofu, the doctor.  And I was
thinking about adding -chan and -san to Akane and Kasumi, respectively, yet
I felt that it would detract from the feel of Tofu's words to Kasumi and
Akane.  I feel it only necessary to use Japanese sporadically and 'when
needed', not all the time.  Ah well.  That's just me.
