Tooth Fairy AWOL

So, the tooth fairy forgot to come to get my daughter's tooth the other night.  I asked both of the little girls why they thought she had forgotten to come.  Abby thought she might have been busy or on vacation.  Miranda thought that maybe she couldn't come because it was raining and snowing. She informed me that when it is raining butterflies can't fly because it ruins their wings.  She thought that it probably would have ruined the tooth fairies wings if she had tried to fly in the rain/snow.
