BRILLIANT WIFE!! (FUNNY STORY)

My dear husband,
I have received your letter and appreciate your candidness regarding my age of 57. I would like to take this moment to remind you that you, too, are 57 years old. As you are aware, I work as a mathematics teacher at our local college. I wish to inform you that while you are reading this, I will be at the Hotel Fiesta with Michael, one of my students who also serves as the assistant tennis coach. He is youthful and, similar to your secretary, is 19 years old. As a successful businessman with a strong understanding of mathematics, you will recognize that we find ourselves in a comparable situation, albeit with one minor distinction – 19 divides into 57 more times than 57 divides into 19. Consequently, I will not return home until sometime tomorrow.
