Once, when I was a very little girl in a bubble bath, I asked my father why I had a belly button. He was sitting on the toilet lid reading while I splashed. He peered at me over the top of his book.
“So you know where your center is,” he said.
“Why do I need to know where my center is?” I asked.
“So you don’t lose your balance,” he said. “Your center is where all the different parts of who you are come together. It used to connect you to your mother and to the beginning of human history in Africa.” I cannot be certain this is true, but when I remember him saying this, I hear his voice catch on the word mother.
