Well, Peter, you have to do better than that next time, won't you?
Have I really got to do those exams again, Dad?
Of course, you have. You must try harder this time.
And must I go back to school?
No, you needn't do that. You'd better get a part-time job somewhere and go to evening classes.
But Dad, I should be working full-time at my age. I'm nearly 17.
You ought to have worked harder then you wouldn't have failed your exams. You have to take a job and study.
What else I've got to do? Join the army?
