(view spoiler)[I am a little confused about what actually happened with the sperm mixing. It seems as if the idea was to mix the donor and husband's sperm so that there is at least a chance that the husband's will prevail, so to speak. But the author writes as if her parents knew for sure that it was only the donated sperm that was used and chose to ignore the fact, for which omission she blames them. Or am I missing something?

Maine thank you, London....in that case i find it odd that she blames them so deeply for deceiving her when they were probably deceiving themselves as much. It seems to me the more interesting question for her to ask herself is....why does it matter so much? Not that it shouldn't, she has every right to feel what she feels, but what is the difference when you find that someone is the same in every way regarding how they treated you but happens not to share genetic material. Startling, maybe, but hardly a betrayal...at least in my book.

When Shapiro spoke with the one person she could find who worked with Dr. Ferris (sp?), he told her that the parents would have been told there was a "treatment" that increased the likelihood of insemination. So her parents may have not asked any further questions. They had a hint that the doctor could be using someone else's sperm, but maybe never acknowledged it. (hide spoiler)]
