A guy in my office got the flu the other day. Today I seem to have come down with it, too.
Very likely. You have a slight fever. Do you have a headache, too?
Yes. I wonder if you could do something to help me recover soon, because I'll be on a business trip in two days.
Well, you have to let your flu run its course. You must stop working and stay in bed to get plenty of rest. Usually it will take 4 to 6 days to make a full recovery.
But I'm going on a business trip in two days!
Maybe you'll have to cancel it or postpone it. If you go out while you are sick, it won't help you recover. You may even pass your disease on to others.
