One morning a mailman walked up to a house. He rang the bell.
A moment later a window of the house opened, and a woman put her head out.
"What’s it" she wanted to know.
"I’ve got a package(包裹) for Mrs Smith," the mailman said.
"Is it registered(挂号的)" the woman asked.
"Yes,’ the mailman said.
"Is it a big package or a small package" the woman wanted to know next.
"It’s quite a big package," the mailman told her.
"I see." The woman thought for a minute, then she said, "Who is it from’
The mailman looked at the return address on the hack of the package
"It’s from Jones and Jones in London," he said.
Now the woman was very interested. "From Jones and Jones, eh" she said. "That’s a very expensive shop. What’s in the package"
"Madam,’ the mailman said, becoming quite angry with the woman, "I don’t know. Why don’t you come down and take the package from me, then you can open it and find out"
"Oh, I can’t do that," the woman said.
"Why not" the mailman said.
"Because I’m not Mrs Smith,’ she said. "You’ve come to the wrong house. Mrs Smith lives next door.\
