It's Sandra's thirteenth birthday. She asked her friends and classmates to come to her party. Her grandparents, uncle and aunt also came. They had a party in Sandra's home. They sang, danced and told some interesting stories. They had a good time here.
But a boy about ten was sitting in the corner. He was watching the other children. He listened to the stories carefully. Sandra found him and went to him with some ice-cream(冰淇淋).
"Hi, Robert!" said Sandra." Why not play with us? You're a smart boy. You can tell us interesting stories."
"I, I…" the boy didn't know what to say. Mr. Hill saw it and said, "A child was smart when he was young, but maybe stupid(愚蠢的) when he grows up(长大)！"
"Uncle, you can't say that!" Sandra said.
"That means that you were smart when you were young, sir!" Robert answered.
