A:Are you feeling better today, Bill?
B:Well, it's hard to say. I cough a lot in the evening.
A:You'd better give up smoking. It's bad for your health.
B:You're right, but you know, it's hard to give up an old habit.
A:But you should make up your mind first.
B:You know, I often have to work til late at night. I need something to keep me awake.
A:Why don't you go to bed and get up early? You'll have the same time for work.
B:Thank you for your advice! I'll try it.
