One night during the depression, I got an encouraging call from my youngest brother, David, who had heard I was struggling. Near the end of our conversation, he said something that has stayed with me in the years since then. “Karen, did you ever see that movie with Tom Hanks where he gets stuck on the island?” Yes, I told him, I’d seen that movie. “For four years he was trying to get off that island,” my brother said, ”and then one day the tide brought in that piece of metal that he could use for a sail. He wasn’t expecting it. He couldn’t have known it was going to come in with the tide. But it saved him. You never know what the tide will bring in that will save you.”
