I hope I won't oversleep tomorrow. I have to catch the first flight to Sydney at 6 o'clock in the morning. Why not register a wake-up call at the reception center? If I buy a pet, will you take care of him while I'm away from the house? Sure I will, if you take care of mine while I'm on vacation. Why did you come to the class late? I left a message with your sister about the time change. You left the message with her? She has a really short memory. I have decided to take another term of American History. No kidding! In this case you can give me many suggestions on this course. I will start the introductory course next week.
