That's what the book was really about. The fact that some words of unrestrained cruelty could unleash a chain reaction that ruins lives. When you're with someone from the time they're born, when you are solely responsible for their very survival, how infinite are the chances of being thoughtlessly cruel.
I am sorry, my son, for making you feel worthless because you didn't conform, for making you feel like a burden because you made my life difficult. At least that's what you heard. It wasn't what I meant. I was angry at you for making yourself suffer. Your suffering was my suffering. Your well-being was my well-being. You were never separate from me. I told you I loved you more than anything. But that doesn't begin to describe it. I love you more than being.
