The mother-in-law arrives home from shopping to find her son-in-law, Paddy, in a steaming rage and hurriedly packing his suitcase.

“What happened Paddy?” she asks anxiously.

“What happened? I’ll tell you what happened! I sent an email to my wife telling her I was coming home today from my fishing trip. I get home… and guess what I found? Your daughter, my wife, Jean, naked with Joe Murphy in our marital bed! This is unforgivable! The end of our marriage. I’m done. I’m leaving forever!”

“Ah now, calm down, calm down Paddy!” says his mother-in-law. “There is something very odd going on here. Jean would never do such a thing! There must be a simple explanation. I’ll go speak to her immediately and find out what happened.”

Moments later, the mother-in-law comes back with a big smile. “Paddy, there, I told you it must be a simple explanation… She never got your email!”

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. Therefore, after reading this letter, I hope that you will not be upset that I will be spending the evening at the Comfort Inn Hotel with Chantelle, my 18 year old secretary.

Please don’t be upset. I shall be home before midnight.

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 mathematics teacher. 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 rugby coach. He is young, virile, and (like your secretary) 18 years old.

As a successful businessman with a mathematical brain, you will understand that we are in the same situation, but 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 !!!
