My Dear Wife,
You will surely understand that I have certain needs that a woman of fifty-four years cannot satisfy. I am very happy with you and value you as a good wife. Therefore after reading this letter, I hope that you will not wrongly interpret the fact that I will be spending the evening with my 18-year-old secretary at the Comfort Hotel. Please don't be perturbed. I shall be home before midnight.
When the man came home, he found the following letter on the Dining Room table:
My Dear Husband,
I received your letter and thank you for your honesty. I would like to take this opportunity to remind you that you are also fifty-four years old. At the same time I would like to inform you that as you read this, I will be at the Hotel Fiesta with Michael, my tennis coach, who like your secretary, is 18 years old. As a successful businessman with an excellent knowledge of mathematics, you will understand that we are in the same situation - although with one small difference.
Eighteen goes into fifty-four a LOT more times than fifty-four goes into eighteen. Therefore, I won't be home until lunchtime tomorrow.
Keith
