A letter was left on the dining room table.

My dear wife: You will surely understand that I have needs that your 54-year-old body

can no longer supply. 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 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 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 math you will understand that we are

in the same situation 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.
