There was a newlywed who called me about his wife; he had e-mailed me on Facebook, and I gave him my number. “How do you know you won’t get sick again?” he asked, aggressively. “I don’t know. I really can’t answer that.” “How can you be sure?” “I can’t be. This is just what the doctors are telling me.” “And how come you got better while my wife is still sick, even though she was diagnosed before you?” “I, I don’t know.” Two weeks later, he called me back. “She’s dead. She died last week. I thought you should know.”
