                                                         My Wife Is Ill

     Mr Jackson was a doctor. A lot of patients went to see him and he was very busy and had little

time to rest in the daytime. One night, when he looked over the last patient, it was five to one.  He was

too tired to say a word and lay down at once.  As soon as he fell asleep, a farmer began to knock at the

door and got him up.

     "My wife is ill," shouted the farmer. "Please go and look her over. " Mr Jackson had to go

out with the farmer. It was the coldest night of the year and the road was covered with snow and

ice. The farmer lived far away from the town and they went through a forest, crossed two rivers

and a mountain. It took them three hours to get to the short, small house. And they were both

tired, cold and hungry.

     The woman stayed in bed. She looked fine. Mr Jackson looked her over carefully and found

there was nothing serious with her. He became angry. He called the farmer out and said,"Your

wife is strong and healthy, you know. Why did you ask me to come here late at night?""l'm sorry, sir,"

said the farmer.  "My wife never does anything at home.I thought she was ill.

when you're free, we'll pay you nothing."
