Eight-year-old Sally brought her report card home from school. Her marks were good . . . mostly As and a couple of Bs. However, her teacher had written across the bottom: Sally is a smart little girl, but she has one fault. She talks too much in school. I have an idea I am going to try, which I think may break her of the habit.

Sallys dad signed her report card, putting a note on the back: Please let me know if your idea works on Sally because I would like to try it out on her mother.
