We looked around that ordinary kitchen — the kitchen where I had packed a thousand school lunches — and we started, both of us, hunting for the things that might keep us alive.

I have thought since about how much I asked of my son in those minutes, and it humbles me.

He was ten years old.

He had just watched his father poison him.

His body was heavy and wrong with whatever was in it, his mind was foggy and terrified, and every instinct a child has in a moment like that is to cry, to cling, to be held and told it isn’t real.

And instead of any of that, his mother put a finger to her lips and told him to be silent and still and to do exactly as she said, and he did.
