One day Mrs Peny went shopping.When her husband came home in the evening，she began to tell him about a beautiful cotton dress."I saw it in a shop this morning，"she said，"and..."
"And you want to buy it，"said her husband."How much does it cost？"
"Twenty pounds for a cotton dress？That is too much！"
But every evening，when Mr perry came back from work，his wife went on to speak only about the dress.At last，after a week，he said，
"Oh，buy the dress！Here is the money！"She was very happy.
But the next evening，when Mr Peny came home and asked，"Have you got the famous dress？"She said，"No.""Why not？"he said.
"Well，it was still in the window of the shop after a month.That means nobody else wants it，So I don't want it either."
