Dear Cassy,
Thanks for reminding me by e-mail that you want to baby-sit our children. In spite of the fact that you are only 15 years old, my wife and I would be willing to consider your application if you can meet a few modest requirements:
1. Submit（提交）three letters from teachers who will prove that you have never failed to follow directions perfectly in class and never failed to hand in a homework assignment（任务）on time.
2. Submit a note from two doctors which says that you are in perfect health, have never been sick, and never will be sick.
3. Submit a document（文件）from your physical education teacher or team coach that proves that you can do each of the following: Run two miles in less than nine minutes, climb an oily rope to a height of twenty feet in thirty seconds while balancing（平衡）a glass of water on your nose, and walk in bare feet over hot coals and broken glass without complaint or injury.
4. Submit letters from at least two mental health experts saying that you have never had a bad thought towards any living being or not living object.
5. Play and defeat five expert chess players with your eyes covered after going without sleep for 48 hours.
6. Wait patiently for two years while we make sure that all your documents are true.
Your loving and trusting friends,
The Smiths
