Ben: You know, mom, in the olden days they use to race ferries.
Me: Race fairies? Really?
Ben: Yes, they really did.
Me: Race fairies? Are you sure?
Me: Wait - you mean fairies like little people with wings or ferry boats?
Ben: Ferry boats!
Me: Yes, you're right! They did use to race ferry boats - not little people with wings because you know there's no such thing.
Ben: Yea, I know.
Ben: So. Mom....are you ready to admit you're the tooth fairy?
Sometimes he is just too smart for his own good!
