Abstract
The title of this paper deserves an explanation—or rather two explanations, one for the portion preceding the colon, the other for that following as the subtitle. The first part is derived from a short essay by Emily Perl Kingsley, written in 1987 in response to questions she had received about what it is like to raise a child with Down Syndrome.1 Kingsley suggests that planning for a child is like planning a trip to some wonderful destination—in her example, Italy. She asks us to imagine the anticipation: searching out guidebooks, learning important sites to visit, the excitement at being able to see things one has heard about an entire lifetime—seeing Michelangelo's David, for instance. But, when the plane.
