What could be a possible alternative ending to A Family Supper?

In my mind, the most immediate area where there could be
an alternative ending proposed would have to be with the relationship between the son
and the father.  One of the most critical issues raised in the book is the gap between
father and son, within generations.  It seems as if the father has made some semblance
of piecing together something that resembles authenticity with how he he asks his son to
stay in Japan.  The son's answer is noncommittal, at best.  This would be where an
ending could be proposed in so far as the son actually begins to piece together the
relationship with his father.  In this ending, generations come together and the theme
of understanding how to configure the past in the face of an uncertain and unclear
future is present.  The opposite of this could be seen, as well.  The father argues that
there " are other things besides work" and with this, the son can become more animated
in his drive to piece together his life after Vicki and away from Japan, once and for
all.  In this, the realization hits the son that he will never be able to say what he
wished to his mother and while his father is making strides to understand a better
present apart from the past, the son has more present and future in front of him.  In
living his own life away from Japan and his own family, the son might be able to
recognize that his own freedom is all that he has and while others might see him in one
light, he might be able to see himself in an appropriate one and this could help to make
all the difference.  In the end, I think that one of two endings on an emotional level
can be present if the son commits to staying with his father, or commits to his own
departure and shows a zeal for life that has been missing thus far in his being in the
world.
