Помогите грамотно сократить текст.
A rich American went to Paris and bought a very strange picture painted by a fashionable modern artist. The American thought the picture was very fine because he had paid a lot of money for it. But when he came to his hotel and wanted to hang the picture up on the wall, he could not tell which was the top and which the bottom of the picture. The American turned the picture this way and that, but still could not decide which was the top and which was the bottom.So he thought of a plan. He hung the painting in the dining-room and invited the artist to dinner. When the artist came, the American said nothing to him about the picture.When the artist began to eat his soup, he looked at the picture many times. When he began to eat his fish, he put on his glasses and looked at the picture again. Before he began to eat his fruit, he got up and walked over to the picture to look at it more closely. At last when they began to drink their coffee, he understood that the picture was upside down."Why, my friend", he said, "my picture is hung upside down".
"Oh, is it?" said the American. "Why didn't you tell me so at once?"
"Well, you see, I was not sure myself at first", said the artist.
