<p>Often children are reluctant to face their responsibilities seriously. Punishments such as banishment to their room for a period of time, taking away favorite toys or games, having "reasonable" sit-down talks, special treats, lavish praise or even bribery such as allowances may make a short-lived difference. However; in this charming children's book the mother finds exactly the right "key" to enlist more cooperation from her heretofore lazy daughter. Young readers get an opportunity to guess what the answer is in a surprise guess at the end of the book.</p>
