Last night was the second night that Sam's tooth lay forgotten, by you, under his pillow. The tooth is a first molar, in excellent condition. It is housed in an envelope of such extraordinary creativeness that you can't possibly miss it. Plus, it says "Tooth In Here", in big letters.
Sir, we understand that you are very busy. We realise that you cannot always get to our house, far from town as it is, as quickly as you should. But leaving my Darling Sam penniless for yet another day is hard, Tooth Fairy. Very hard. Your neglect of this boy's lovingly polished and dried tooth (and it IS a beautiful tooth!) has caused such distress. Your very existence has been questioned, by both Sam and Max.
Max has a very loose tooth now too, and the suspense!! For if you don't come tonight for Sam's tooth, if you don't leave him a crisp twenty, then Max may look to other markets for his soon-to-fall-out front tooth.
Tooth Fairy, I trust that our long-standing business arrangement is as valuable to you as it has hitherto been to us. Kindly give this situation your immediate attention. We anticipate your arrival tonight.
Thank you, Sir, for your valuable business in the past, and your timely attention to this matter.
(Edited: Yes, folks, the Tooth Fairy has been. All is well. for more Tooth Fairy action, see here, or search "tooth" up there in the search thingy. Our Tooth Fairy has had many adventures!)
