When the man came home late that night, he found the following letter on the dining room table:

My Dear Husband,
I received your letter and thank you for your honesty
about my being 54 years old . I would like to take this opportunity to
remind you that you are also 54 years old . As you know, I am a math
teacher at our local college . I would like to inform you that while you
read this, I will be at the Hotel Fiesta with Michael, one of my
students, who is also the assistant tennis coach. He is young, virile,
and like your secretary, is 18 years old .
As a successful businessman who has an excellent knowledge of math, 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 home until sometime tomorrow .
