The Tooth Fairy and the Dragon

Or... inside the mind of a three year old

We're driving. She's in the back seat chatting in her cartoony, lilting, little voice, as usual...

Her: Mom? How big are my teeth?
Me: Pretty little.
Her: NO! I mean how BIG!
Me: I'd say about half a centimeter. (I have no idea)
Her: Oh. Someday I will have a loof toof (loose tooth). How will it get loof?
Me: The adult tooth pushes it out of the way, then it gets loose and falls out.
Her: Oh. Then we put it under the pillow for the toof fairy and she will bwing me a beautiful twinket? (trinket)
Me: Ah... yes?
Her: Mom, what's a twinket?
Me: Um, it's a little shiny toy or doll or.... maybe a quarter... (how do you define trinket?)
Her: Will it be from the toof fairy?
Me: Maybe, or maybe it'll be from me!
Her: Mom? Is the toof fairy weal (real) or just make belive?
Me: She's mostly make believe, but if you put your tooth under the pillow, you will get a trinket! Or... maybe a quarter.
Her: Oh. Mom? When will I be a dragon?
