So, this time, the tooth fairy remembered to come (that very night); she found the note; she did not leave a return note saying that she try again tomorrow when the room was a bit less messy; she made no judgements about how the cash should be spent; she left the right amount without asking that the child leave some change for which she would return; and it was generally all round the best job she’s ever done in this place. Except she forgot to take the tooth.
There’s probably only two teeth left of the ones that are supposed to fall out. She should be able to get it right at least once.
