My dear husband,I received your letter and thank you for your honesty about me being 57 years old. I would like to take this opportunity to remind you that you are also 57 years old.As you know I am a maths teacher ,
at our local college. I would like to inform you that while you read this, I will be at the Hotel Fiesta with Michael, one of my students, who is also the assistant tennis coach. He is young virile and, like your secretary, is 19 years old.As a successful businessman who has an excellent knowledge of maths, you will understand that we are in the same situation, although with one small difference – 19 goes into 57 more times than 57 goes into 19. Therefore, I will not be home until sometime tomorrow.
