The tooth fairy visited our house recently, which made me remember the time—many years ago, when tooth redemption brought only a quarter—that the tooth fairy kept forgetting to claim the tooth under my pillow. After a week, I put a sign on my bedroom door: TOOTH STOP! The next morning, I had my quarter, and a signed note. The tooth fairy explained that he had an extraordinarily large territory that included the Indian Ocean, and apologized for having been delayed by recent monsoons. The note was signed “Prince Oberon.”
