Excuse me , Mr . Li . I have something to discuss with you .   I'm in a bit of a hurry , Miss Liu . Can you wait for a minute ?   I would really appreciate it if we could talk for a few minutes now . It's about the overtime you've asked me to put in .   All right . What's the problem ?   I really can't work overtime . Because my husband has been ill recently , I must take care of him .
