I was arguing with a friend yesterday about ds puzzle so i decided to post it here.. I think the answer should be d little boy my friend said it's the grandpa. Ur opinion is needed pls

Boss says to secretary, "We are
travelling abroad for the week, so make
arrangements."
Secretary makes a call to her husband, "My boss
and I will be travelling abroad for the week, so
look after the kids."
Husband makes call to secret lover, "My wife is
going abroad for the week, so let's spend the
week together."
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."
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."
Grandpa makes a call to his Secretary,
"I'm afraid we won't be travelling again. My
grandson and I are going to spend the week
together."
Secretary makes a call to her
husband, "My boss has some personal matters to
attend to, so our trip is
cancelled."
Husband makes a call to secret lover, "We cannot
spend the week together, my wife has cancelled
her trip."
Secret lover makes a call to little boy, "We will
still have classes as usual this week as I won't
be busy again."
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."
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."
Question is, who is controlling this circle?

i'll go for the granpa, he is the senior man

Grandpa is in control.

If d little boy had class dat week grandpa will still continue with the trip nw

The little boy of course

Obviously the little boy
