There was a farmer in a small village. One day, he had a headache. He heard that there was a famous doctor in the nearby village, so he decided to go to visit her. His neighbor told him that he had to pay the doctor five dollars for the first visit, but only one dollar for the second visit. It was cheaper. Later he came up with a good idea. Then he went to see the doctor with only one dollar.
There were many sick people in the doctor's home, so the farmer had to wait. About one hour later It was his turn.
"Morning, doctor. I am here again. The farmer said to the doctor. And then he gave the doctor one dollar. The doctor knew this was the first time that he had been here but she wasn't angry about it. She examined(检查)him and then said, Well, sir, there is nothing serious with you. Please continue to take the medicine I gave you last time. "
