In the car this morning, completely out of the blue:
The Girl to Thing Two: "Do you know a word that starts with P and ends with S?"
Me to her (alarmed at where she could possibly be going with this): "Do you know any words that start with P and end with S?"
The Girl: "Of course. Platypus!" (She's a fan of the kids' TV show Phineas and Ferb, which features one of these creatures.)
Me: (greatly relieved)
Not sure if this episode speaks more to her precocious spelling ability or my dirty mind!
