I'm too tired now . I've already worked for 12 hours overtime !   God ! Don't you think they should get you an assistant ?   Yes , they were supposed to , but so far nobody's turned up , and I have to do the work alone . This is the first break I've had all day .   They're really running you into the ground . Why don't you ask for some time off ? You could take a long weekend and have a good rest .   I'm afraid I can't before I finish this project .   You'd better pay more attention to your health .   I will , thanks for your concern .
