Life is not a book, Alex. And it can be over in a second. I was having lunch with my mother at Daley Plaza and a man was killed right in front of me. He died in my arms. And I thought, "It can't end just like that on Valentine's Day." And I thought about all the people who love him, waiting at home, who will never see him again. And then I thought, "What if there is no one? What if you live your whole life and no one is waiting?"
