Teacher makes a call to her student

to inform him:”I’m busy tomorrow, so our class will be off”. The student makes a phone call to his dad:”I’m off tomorrow, let’s go picnic”. Dad makes a phone call to his secretary immediately:”Hey, I’m busy tomorrow, let’s date someday else”. The secretary makes a phone call to her husband:”Hey honey, I won’t be going to the business trip tomorrow, let’s hang out”. The husband makes a phone call to the teacher:”Hey, Sorry, my wife won’t be leaving tomorrow, we can’t meet”. The teacher calls the student:”Forget what I said. Tomorrow we go to school”
