Are you going out again ?   Yes , I'm going to the cinema , dad .   You mustn't go to bed very late . Can you be home before nine .   Oh , I won't be back so early . The film will be over at nine . Can I have the key to the bicycle ?   No . I won't let you ride a bicycle late at night .   Oh , dad , I'm not a child . I'm 17 already . I'll come back as soon as the film is over .
