Happiness is being an aunt. Also, a book recommendation

I am getting some much-needed rest and rejuvenation with the help of some little girls in Florida. Recent conversations: Codename Isis (aged 3) (in the living room, building a puzzle): Where is the other puzzle piece? Codename Phoenix (aged 3) (thoughtfully): Science will solve this mystery. Isis (in the park): How will we get these ants off the tree stump? Phoenix (thoughtfully): A woodpecker will solve this mystery. Isis and Phoenix (in my bed this morning): Kristin, Kristin, can we help you put your tooth protector in its case? (That's the mouthguard I wear when I'm sleeping, being a tooth grinder. For some reason, of all my possessions, this is their favorite. It has fascinated them for years.) Me: Of course! Phoenix: It doesn't fit on our teeth. Isis: It only fits on big people teeth. Me: Actually, the dentist made it so that it only fits on my teeth! It doesn't fit on anyone else's teeth in the world. Isis (extremely grave): That's sad. *
