The day the Pulliams left, Anna got a new haircut. She had begun to chew on her pretty long hair (I used to do that, too - hair, strings to my hat or hood, fingernails), and in exasperation I said, "If you keep chewing on your hair I'm going to cut it." First rule in parenting: Never threaten something you don't intend to follow through with. Anna looked at me "Would you please? I want it just like Abby's."
