You’ll understand that I have certain expectations that, at 57 years old, you no longer quite meet. Please know that I still appreciate you and consider you a good wife. With that in mind, I hope you won’t take it the wrong way when I say that I’ll be spending this evening with my 19-year-old secretary at the Comfort Inn.

There’s no need to worry; I’ll be home before midnight.

When the husband returned home late that night, he found this note waiting on the dining table:

My dear husband,

Thank you for your honesty, especially at the age of 57. I want to remind you that you are also 57.

As you know, I teach math at our local college. While you’re reading this, I’m spending time at the Hotel Fiesta with Michael, one of my students and the assistant tennis coach. He’s young, energetic, and, like your secretary, 19 years old.

As a businessman with a strong grasp of math, you’ll realize that we are in a similar situation, except for one key difference: 19 goes into 57 more often than 57 goes into 19. So, I won’t be home until tomorrow.
