Finn climbs out of bed in his sweet saggy underpants, rubs the sand out of his eyes. God, I love him. His cheeks have tiny sleep wrinkles on them from the pillowcase. He’s only nine—still on the verge of being a small boy. But soon he, too, will come to treat me with utter contempt. When Jack was born, I looked at the tiny baby in my arms, suckling, pig-perfect, kissed his eyelids and said, “I love you so much, and someday, no matter what I do, you will hate me. At least for a little while.” It’s a fact of life.
