Well....
Boss says to his secretary,
“We are traveling abroad for the week, so make arrangements.”
The secretary makes a call to her husband,
“My boss and I will be traveling abroad for the week, so look after kids.”
The husband makes call to secret lover,
“My wife is going abroad for the week, so let’s spend the week together.”
The secret lover makes a call to a little boy whom she is giving private lessons,
“I’m going to be busy throughout the week, so you need not come for classes.”
The little boy makes call to his grandfather,
“Grandpa, I don’t have classes for the week, because my teacher is going to be busy. Let’s spend the week together.”
The grandpa makes a call to his secretary,
“I’m afraid we won’t be traveling again. My grandson and I are going to spend the week together.”
The secretary makes a call to her husband,
“My boss has some personal matters to attend to, so our trip is cancelled.”
The husband makes a call to secret lover,
“We cannot spend the week together, my wife has cancelled her trip.”
The secret lover makes a call to little boy,
“We will still have classes as usual this week.”
The little boy makes a call to his grandfather,
“Grandpa! I’m sorry we won’t be able to spend the week together. My teacher called and said that I have to attend classes.”
The grandpa makes a call to his secretary, “Change of plans! My grandson is no more coming. So we are still travelling this week. Make arrangements.”
