An old woman walked into a clothes shop between a cinema and a bank. She asked the salesgirl to let her have a look at the new dress. However, the girl didn't say a word. She just stood there. The old woman asked the girl to show her the new dress again. But she said nothing. The old woman smiled. She 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 the salesgirl heard that, she shouted at the old woman, "What? Did you call me a model girl?" The old woman was very surprised. She said "Oh, dear. What a surprise! The model can speak."
