Has a doctor ever given you a note to take to the chemist for some medicine? Are you able to read the note easily? Some doctors write clearly , but most doctors do not. Chemists（药剂师） have more chances to read doctors’ notes, but sometimes doctors write so badly that even the chemist can’t read them.

One day a lady wrote to a doctor inviting him to have dinner at her house. The doctor wrote an answer, but he didn’t write clearly and the lady couldn’t read it.

“What shall I do?” she said to her husband, “I don’t know whether he is coming or not. I don’t want to give him a telephone call and say that I can’t read his writing.”

Her husband thought a moment, then he had an idea.

“Thank you,” said his wife. “That’s a very good idea.”

She went to the chemist’s shop and gave the doctor’s note to the chemist. The chemist looked at it very carefully. Then he said politely, “Could you wait a moment, madam?” He went to the back of the shop. After a few minutes he returned carrying a large bottle. He gave the bottle to the lady and said, “Three times a day and one spoonful at a time.”
