Mr. Jones and Mr. Brown work in the same office. One day Mr. Jones says to Mr. Brown, "I'm going to have a small party at my house on Monday evening. Would you and your wife (妻子) like to come?"
Mr. Brown says, "Thank you. I'd love to, but let me ask my wife first." So, Mr. Brown goes to the other room and telephones his wife. Then he comes back and looks very worried.
"What's the matter?" asks Mr. Jones. "Is your wife at home?"
"No," answers Mr. Brown. "She isn't. My little son answers the telephone. I ask him, 'Is your mother there, David?' He answers, 'No, she isn't in the house. She is somewhere outside looking for me.'"
