Jack left before the end of the meeting. He had to go home early. In Britain many children have to wear uniform when they go to school. When you come to London again, you must come and see us. Last night Don became ill suddenly. We had to call a doctor. You really must work harder if you want to pass the examination. I'm afraid I can't come tomorrow. I have to work (will have to work) late. I'm sorry I couldn't come yesterday. I had to work late. Paul doesn't like his new job. Sometimes he has to work at weekends. Caroline may have to go away next week. We couldn't repair the car ourselves. We had to take it to a garage.
