M: Let’ s back up. Where was I?
W: You were talking about your trip to South Africa. I bet you had a great time.
M: Yes, we did. In fact, you know what we encountered.
W: A long-last friend?
M: Come on! A lion.

M: Our flight will be delayed by 6 hours. That means it won’t be leaving until 3: 30 in the afternoon.
W: What shall we do in the meantime?
M: Let’ s find some seats in the quiet part of the terminal to take a nap.
W: Good idea. I am pretty tired.
