Once a rich woman asked Martin Brown, a famous singer, to her house. She wanted him to sing for her friends, but she didn't ask him to have dinner with them. She told him to eat downstairs with the servants.

The singer was surprised. But he said nothing and went downstairs. After the meal he stood up and said to the servants, "Now, my good friends, I shall sing for you."

Of course, the servants were pleased. He sang them several songs. When they asked for more, he sang more. At 9 o'clock the rich woman asked the singer to come up to the sitting room. When he came in, he saw all the friends sitting and looking at him.

"We are ready now, Mr. Brown," said the woman. "You may begin."

"Ready for what?" asked the singer.

"For your songs, of course, "she answered. "But I have sung already!" said Mr. Brown, "and I can't sing twice in one evening."

"You have sung already!" said the rich woman in surprise. "But when? And where did you sing?" "Just now, downstairs." "Really?" she cried.

"Yes, madam," said the singer. "I usually sing for the people after I have dinner with them, you know."
