An old lady walked into a clothes shop. She asked the shop girl to let her have a look at a new dress. But the girl didn’t say a word and she didn’t move a little. The old lady asked the girl to show her the new dress again. And she said nothing again. The old lady looked at the girl and said to herself, “I am too old to see well. I don’t know who is a model girl and who is a real girl.” When she heard this, the real girl shouted at the old lady, “What? Did you call me a model one?” The old woman was very surprised. “Oh, dear me.” She said, “The model can speak. Then it must be a new kind of robot.”
