As a novelist, I mined my history, my family and my memory, but in a very specific way. Writing fiction, I never made use of experiences immediately as they happened. I needed to let things fester in my memory, mature and transmogrify into something meaningful.

In every union roles are assumed, some traditional, some not. My husband used to pay his own bills, I used to call my own repairman. But as marriages progress, you surrender areas of your own competence, often without even knowing it.

I did not want to raise a genetically compromised child. I did not want my children to have to contend with the massive diversion of parental attention, and the consequences of being compelled to care for their brother after I died. I wanted a genetically perfect baby, and because that was something I could control, I chose to end his life.

Think about it, I say. How many straight men maintain inappropriately intimate relationships with their mothers? How many shop with them? I want a gay son. People laugh, but they assume I'm kidding. I'm not.

The idea of going down to Central or South American and taking ayahuasca and shitting my pants and puking in a circle of overprivileged white people is not my idea of a good time. That's not going to happen.

Well, you know, I was raised by a 1970s feminist. My mom had a consciousness-raising group. I used to sit at the top of the stairs and listen to them.

By the time the children go to bed, I am as drained as any mother who has spent her day working, car pooling, building Lego castles and shopping for the precisely correct soccer cleat.
