A letter was left on the dining room table.


"My Dear Wife,


You will surely understand that I have certain needs that your 54 year old
body can no longer supply. I am very happy with you and I 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 Inn Hotel. Please don't be perturbed - I
shall be back home before midnight".


When he 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 54 years old. At the
same time I would like to inform you that while you read this, I will be at
the Hotel Fiesta with Michael, my tennis coach who, like your secretary, is
also 18 years old. As a successful businessman and with your excellent
knowledge of maths, you will understand that we are in the same situation,
although with one small difference: 18 goes into 54 a lot more times than
54 goes into 18. Therefore, I will not be back before lunchtime tomorrow".
