When I started dating Daniel, he told me the hardest part on the second date.“I have two daughters,” he said. “Grace is six. Emily is four. Their mom died three years ago.”He said it in that careful, even tone people use when they are trying not to fall apart in public.I reached across the table and touched his hand.The girls were easy to love, though they were nothing alike.“Thank you for telling me.”He gave me a tired smile. “Some people hear that and decide dinner is over.”
