Mrs Green sees an ad(广告)in a newspaper for a nice bed in a shop. It costs 100 dollars. Mrs Green likes it, so she goes to the shop. The shopkeeper shows one to her. Mrs Green has a look at it and says, "There aren't any beautiful pillows(枕头)on this bed, but there are many on the bed in your ad. "
"Yes, madam, that is an ad," answers the shopkeeper. "If you want a bed the same as the one in the ad, you need to pay lo dollars more."
Mrs Green isn't happy. Then she says, "That's dishonest."
"Well, madam," answers the shopkeeper. "Look, there is a girl on a bike in an ad in your newspaper too, but can you buy the bike with the girl?"
