The doctor's Handwriting

Mrs South is excited these days. A sudden terrible disease hardly killed her son two months ago. She and her husband took the poor boy to several hospitals, but few doctors could save him. Watching their helpless son struggling for a bare subsistence(在死亡线上挣扎), the woman’s and her husband’s hearts were broken. At that moment, one of their friends introduced Mr Young who worked in a small hospital to them. Thanks to the doctor, their son was saved and he was all right and came out of hospital last week.

The woman decided to ask the doctor to dinner. The invitation was sent to him yesterday. In reply she received a letter which was impossible to read.

“I must know whether he has accepted or not.” said Mrs South.

“If I were you,” suggested her husband. “I should take it to a chemist(药剂师). He can always read doctors’ letters, however badly written.”

The chemist looked at the notepaper for a while, without waiting for Mrs South’s explanation, and handed her a bottle.

“Here you are, madam,” he said. “That will be two dollars.”
