Eight-year-old Nina brought her report card home from
school. Her marks were good... mostly A's and a couple
of B's. However, her teacher had written across the
bottom:

"Nina 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."

Nina's dad signed her report card, putting a note on the
back:

"Please let me know if your idea works on Nina because I
would like to try it out on her mother."
