LETTER TO THE WIFE.. To my dear wife, you will understand that I have certain needs, and you at 54 can no longer satisfy them. I an very happy with you and value you as a good wife, so after reading this letter I hope that you will not wrongly interpret the fact that I will be spending the evening with my 19 year old secretary at the Welcome Hotel. Please dont be upset, I will be back before midnight. When he arrived home, he found the following letter awaiting him. To my Dear Husband, I received your letter for which I thank you, I would like to remind you that you are also 54 years of age. As you know I am maths teacher at the college. I would like to tell you that while you read this, I will be at the Beach Hotel with John, one of my students, who is also assistant rugby coach, he is young, virile and like your secretary 19 year s old. As a succesful business man with an excellent knowledge of maths you will realise that we are both 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 be home sometime tomorrow.
