Mr. Jones and Mr. Brown work in the same office. One day Mr. Jones says to Mr. Brown, "We're going to have a small party at our house on Monday evening. Would you and your wife like to come?"
Mr. Brown says," Thank you very much. That's very kind of you. We're free (有空) that evening, but let me ask my wife first." So Mr. Brown goes to the other room and makes a telephone call (打电话) to his wife. Then he comes back and looks worried.
"What's the matter?" says Mr. Jones. "Is your wife at home? No, "answers Mr. Brown, "she isn't there. My small son answers the telephone. I say to him, 'Is your mother there, David?' and he answers, 'No, she isn't in the house.' 'Where is she?' I ask. 'She is somewhere outside (在外面)'.'What's she doing?' 'She is looking for me.'"
