Away from school

@rondetto Said

The telephone rings in the principal's office at a school.
"Hello, this is Derby secondary," answers the principal.
"Hi. Jimmy won't be able to come to school all next week,"
replies the voice.
"Well, what seems to be the problem with him?"
"We are all going on a family holiday," says the voice. "I hope
it is alright."
"I guess that would be fine," says the principal. "May I ask who
is speaking?"
"Sure. This is my father!"
