I filled out a questionnaire over the weekend about family patterns and was shocked again by how little I remember of my childhood. But what particularly struck me is that I have only one specific memory of my sisters from before I turned 15. My (half) sisters are 6 1/2 and 10 years younger, so we didn't play together that much, and my full sister is moderately to severely retarded. But as I look at my memory I seem to have been extraordinarily self-centered. I didn't see anything but myself. Is that just the way children see the world or was that my defense from the harm that was done to me?
