A young American doctor was sleeping when suddenly his doorbell began to ring. It was already midnight. But what could the doctor do? He had to put on his coat and go downstairs.

When he opened the door, he saw a man standing with his hat in his hand. “How do you do, sir?” said the man. “Can you come at once to a place out of town? It’s quite far but you have a car and I can show you the way.”

“Certainly,” said the doctor, “I’m quite ready. I can come at once.” In a few minutes the car was standing at the front door, and the man got on the doctor’s car. They drove on for a long time, then the man said, ”Here we are. This is my home. Now I can pay you and you can go back to town.”

“But I must see the patient,” the doctor said, “How can I go back without seeing the patient? Where is the patient?”

“There is no patient,” explained the man, “Nobody is ill. I live here. You see, one must go home from a town, mustn’t he? There are no taxis at this time of the night, but a doctor often makes night calls, so excuse me. Here is your money. Thank you, doctor. Good night.”
