My Dear Wife,
You will surely understand that I have certain needs that you, Being 54 years old, can no longer satisfy.
I am very happy with you and I value you as a good wife, however, after reading this letter I hope you will not wrongly interpret the fact that I will be spending the evening with my 18 years old secretary at the Comfort Inn Hotel. Please don't be upset, I shall be back before midnight".
When the man came home late that night he found a reply of his 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,he is 18 years old.
You being a successful businessman with 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."
THE HUSBAND FAINTED
