“ So much time and energy, so much love and learning had gone into those long years of motherhood, and now, between a morning and a morning—or so it felt—they were over. It seemed that mothers of daughters had a more extended role but she knew that she was lucky to be allowed any part in her boys' lives and tried hard to be grateful and undemanding. It wasn't always easy, when she loved them so much, to practice detachment.... Odd that the last of the parenting skills should be the most painful: the final act of letting go. ”
