When you are ill, you will see a doctor. The doctor will write a note to take to the chemist for some medicine. Chemists are usually good at reading doctor’s notes. But sometimes doctors write too badly and even the chemists can’t read them.

One day a woman wrote to a doctor to invite him to have dinner with her family in the restaurant. The doctor wrote an answer, but he wrote too badly and the woman could not read it.

“What shall I do?” she asked her husband. “I don’t know whether he is going to come or not. I don’t want to call him and say that I don’t understand him.”

Her husband thought for a few minutes and then he had and idea. “Take it to the chemist,” he said. “He will be able to read it for us.” The woman went to the chemist’s shop and gave the doctor’s “note” to him. The chemist looked at it for a long time.

“Could you wait a moment, Miss?” he said. Then he went to the back of the shop. After a few minutes he came back, carrying a large bottle(瓶子).  He gave the bottle to the woman.

“Take one spoonful(一匙) every day,” he told the woman.
