“Is this the doctor's office?”
“This is his residence.”
“Pshaw! I wanted his office.”
“The doctor 'phoned me about ten minutes ago that he would be out for half an hour and asked me to answer the 'phone in his absence,” Mary explained, pleasantly.
“Oh,” said the voice, somewhat mollified, “I'll just call him up when he gets back. You say he'll be back in half an hour?”
“In about that time.”
She went back to her work, which happened to be upstairs this morning, leaving the doors ajar behind her that she might hear the 'phone. In two minutes she was summoned down.
“What is it?”
“Is this the doctor's office?”
“No, the residence.”
