The Tooth Fairy drinks, you know. At least she does round our way. Time and again she fails to collect teeth left out, clearly marked for that age old transaction. Then on the second night she seems to be leaving £2, twice the usual rate, presumably in response to a fit of guilt. It then often takes a third night for the tooth itself to be harvested, leading to questions being asked. In response I have been known to come out with wild suppositions, like a glut of teeth in fairy land.
But between you and I, I think she likes a drop. Lets hope Father Christmas has a stronger work ethic. If not, we're all in big trouble.
