Wife and Husband

A businessman sent a fax to his wife:

"To My Dear Wife,
You will surely understand that I have certain needs which you, at 54
years, can no longer satisfy. However, I am otherwise very happy with
you and value you as a good wife. Therefore after reading this fax, 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, and I
sincerely hope you will not be hurt or offended.
Please don't be perturbed, I shall be back home before midnight".

When the man came home, he found the following note on the dining room
table:
"My Dear Husband,

I received your fax and I thank you for your honesty. I would like to
take this opportunity to remind you that we are both the same age. At
the same time I would like to inform you that I, too, have certain needs
which you no longer satisfy. As you read this, I will be at the Hotel Fiesta
with Michael my tennis coach, who like your secretary, is also 18 years
old and very fit.

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 which you will easily appreciate; 18 goes into 54 more
times than 54 goes into 18!! Therefore I will not be back before
lunchtime tomorrow".

P.S.: Your dinner is in the fridge.
