A 54 year old accountant leaves a letter for his wife one Friday evening
that reads:

Dear Wife (that's what he called her):

I am 54 and by the time you receive this letter I will be at the Grand
Hotel with my beautiful and sexy 18 year old secretary.

When he arrived at the hotel there was a letter waiting for him that read
as follows:

Dear Husband  (that's what she called him):

I too am 54 and by the time you receive this letter I will be at the
Breakwater Hotel with my handsome and virile 18 year old boy toy. You being
an accountant will therefore appreciate that 18 goes into 54 many more
times than 54 goes into 18.
