That won't do I'm afraid. I've got a very important report on the computer that must be finished and handed in by 9:00 AM tomorrow. By 10:00 it's too late I'm afraid. Can't you come now? ,M: Well, I'm at a job at the moment and my wife and kids are expecting me home by 8:00 PM for dinner. ,F: I know it's Sunday evening. Can you at least suggest someone else who can work? I've been calling numbers in the phone books and you're the only one that answered. ,M: Just a moment. Don't worry. Where are you now? ,F: I'm at my office. I work in the morning side area. ,M: Well, you're in luck. I have to pass your area on my way home. Now I should be finished here by 7:30, so what about around 7:45? Is that OK? ,F: That's great. Thank you.

I always get super red if I haven't put on sun cream.
(A) M: Do you never put on sunscreen because you are not easy to get sunburn? (B) M: Since you are so easy to get sunburned, why don't you bring an umbrella? (C) M: Just a minute!
