One night on our cruise my friend Mike got really excited about the evening's entertainment: a mentalist. He had to sit in the front row, and for some reason he'd put on a suit, which stood out among all the muumuus and flip flops. I asked him why and he said, "I had a really, really good friend, Rick, who died twenty years ago. He promised me if there was any way he could contact me, he would. And I've been waiting ever since."

I just about cried. Mike is a really sweet Southern man so this didn't surprise me, though his naivete did. "You want a medium," I said, "not a mentalist. A medium talks to the dead. A mentalist asks you to think of a number between one and a hundred, and two minutes later a chicken walks in with the number painted on its ass."

Mike was stunned. "Oh," he said. "So this guy can't talk to the dead?"

I shook my head. Mike's face fell as the realization slowly crushed him. He seriously thought he'd hear from his long-lost friend again.

There wasn't much I could, but I had to do something. "You should definitely talk to the guy, though," I said. "The skills don't seem that far apart. If he asks you to think of a number between one and a hundred, tell him, 'I will, but first do you see an older man near me whose name starts with an R or an L?"
