ОТВЕТЬ НА ВОПРОС
WHY DIDN'T NANCY WANT TO DANCE AND SING?
Then the other children came and played in the garden. They played hide-and-seek. They sang songs and danced. But my little sister did not want to play. She did not want to dance and to sing. And Tom did not want to play.
"I can show you the birthday cake," he said.
So they went to the dining-room, and there on the table they saw a beautiful birthday cake with chocolate roses on it.
"Oh, I like chocolate roses very much," said my naughty little sister.

"I can give you a little rose," said Tom.
He gave my sister one rose, and she ate it up. Then he took one rose and ate it up. My sister ate three roses, and Tom ate three roses. They took the roses with their hands, and there was chocolate on their hands and on their faces. Then they went into the garden to play with the other children.
When Tom's mother saw them, she did not ask any questions. She went to the dining-room and looked at the birthday cake. She was very angry.
Tom's mother told Tom to go to bed, for he was a very naughty boy. And she told my naughty little sister to go home. Nancy was sick all night.
My sister is not a little girl now, but she does not like chocolate roses even today.
