  One morning in London，the weather was very cold，and many people caught a cold．They had to see a doctor，so there were many people in the doctor's waiting-room．At the head of the line was an old woman．The woman did not live in London． She lived in the country．She came here to visit her daughter．She wanted to see the doctor because she got a  bad cold and coughed day and night．

  “If I get there early，I can see the doctor quickly，”she thought．So she was the first in the line．

    She sat nearest to the doctor's door．An American came into the waiting-room，and walked quickly to the doctor's door．The old woman thought he was a queue jumper．She stood up and took his arm slowly，she said，“We were all here before you．You must wait for your turn．Do you understand?”  The American answered，“No，madam．You don't understand! You are all after me! I'm the doctor!”
