Scene: At the library, reading a book about dinosaur track fossils.
— “… You might find dinosaur tracks, too.” It’s true; you could.
— No, I’m not a scientist.
— But you could be a paleontologist when you grow up.
— No, I want to be a papa or a mama.
— Well, you could be a papa and a scientist.
— [thinks] No, I just want to be a papa.
