A husband wrote the following letter for his wife andleft it on the dining room table:

'To My Dear Wife. You will surely understand that Ihave certain needs that you, being 54 years old, can no longer satisfy.I am very happy with you & I value you as a good wife. Therefore, after reading this letter, I hope that you will not wrongly interpret the factthat I will be spending the evening with my 18 year old secretary at theComfort Inn Hotel.Please don't be upset - I shall be home before midnight.'

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

'My Dear Husband. I received your letter and thank youfor your honesty about my being 54 years old. I would like to take thisopportunity to remind you that you are also 54 years old. As you know, Iam a math teacher at our local college. I would like to inform you thatwhile you read this, I will be at the Marriot Hotel with Michael, one ofmy students. He is young, virile, andlike your secretary, is 18 years old. As a successful businessman whohas an excellent knowledge of Math, you will understand thatalthough it mayappear that we are in the same situation, there is one mathematicaldifference:
'18 goes into 54 a lot more times than 54 goes into 18.'

Therefore, I will not be home until sometime tomorrow.'
