Peter: Hi, Sally. Come and have a look at my photos. Sally: Are these the photos you took in Africa, Peter? Peter:     Look, this is a wildebeest. It's an animal in Africa. Sally:       Peter: No, it doesn't. It only eats grass. Sally: Are there a lot of animals in Africa? Peter:       Sally: Oh, this photo looks interesting. What are you doing there? Peter:       Sally: Did you have a good time there? Peter: Of course.
