My beloved wife, You will understand that I have certain standards that you, at 57 years old, can no longer meet. I am quite pleased with you and regard you as a decent wife. So, after reading this letter, I hope you do not misinterpret the fact that I will be spending the evening with my 19-year-old secretary at the Comfort Inn.

Please do not be anxious; I will arrive home before midnight. When the man arrived home late at night, he found the following message on his dining table. My dear hubby, I read your letter and appreciate your candor at the age of 57. I want to remind you that you are also 57 years old.

As you are aware, I am a math instructor at our local college. I’d like to let you know that when you read this, I will be in the Hotel Fiesta with Michael, one of my pupils and assistant tennis coach. He is young, vigorous, and, like your secretary, 19 years old.

As a skilled businessman with a good mathematics background, you will notice that we are in an identical situation, with one little exception: 19 goes into 57 more frequently than 57 goes into 19. As a result, I won’t go home till tomorrow.
