Graham: Oh, I fell asleep. Where are we?
Barbara: We're almost there.
Graham: No, no. I want it to look out of the window to see all the places we flew over. Why didn't you wake me up?
Barbara: You looked very tired. So I didn't want to,
Graham: I was asleep for over three hours. What can you see out of the window now?
Barbara: It looks like desert below, but I think we are near Los Angeles. We went over the Rockies a short time ago. The mountains were absolutely beautiful.
Graham: I can't believe I missed that. I really wanted to see the Rockies.
Barbara: Sorry, Graham. You can sit next to the window when we fly back to New York.
Graham: Thanks. Did you have something to eat? I know you were hungry.
Barbara: Yes. About an hour ago I ate chicken and rice. There was also a dessert, but it had pear in it. So I didn't touch it.
Graham: I'm really hungry now, too. I didn't have any breakfast this morning, either.
Barbara: We can buy something for you. When we get to the airport, you don't like chicken anyway. And the alternative was Spanish omelet, which looked disgusting.
Graham: What other things did you see out of the window? Did you see Chicago and the great legs?
Barbara: Yes, we flew right over Chicago. I could see little boats on the Lake. It was wonderful.
Graham: I can't believe I was sleeping. And I had a dream about flying too.
Barbara: They showed a great movie too. You know the one about Brad Pitt being the manager of the chocolate factory.
Graham: That's not Brad Pitt in that movie. I like that film too. I think we're starting to land.
Barbara: Yes, we aren't so high now. What are we going to do? When we get to Los Angeles,
Graham: We have to make a phone call to your father don't way.
Barbara: Right? Then let's go straight to the hotel to sleep. I'm exhausted.
