My conversation with her the other day:
Erin: Gramma, what do you think the tooth fairy does with all those teeth? (course she did not realize that I know she keeps hers...thank u, Molly)
My response: Hmmmm, well, I'm not sure I know the answer to that.
Erin: Well, I think she saves them all and makes tooth necklaces for all the fairies.
Need I say more??? : )
