My name is Lily. My father is a teacher. His students love him a lot because he is funny. I love him, too, but I think he can be “foolish”  41 .
Once we moved into a new house and had to go shopping to buy new chairs and lights. In the supermarket, I’m interested   42  some of the beautiful lights with good qualities and made my father buy them.
When we got home, my father began to work out how much money we had   43  that day. Suddenly, he stopped. “Something’s wrong.” he said. “I’ve got 30 yuan   44  than I should!”“That’s great,” I said. “You can buy me that   45  book I want.”
Father said nothing. Instead, he counted（數(shù)） how much money he had again and again.
“The salesgirl must have made a mistake. We   46  go back to the shop,” he said.
“Do you have to go back?” I asked. “Nobody will know we   47  too much change(找零). It would be foolish to go back.”
“It wouldn’t be ‘foolish’.” my father said angrily. “It’s called being   48  .” At that moment, I looked into his eyes and knew he was right.
The salesgirl was surprised to see us in the shop again. But   49  we gave her the money, she thanked us a lot.
On my way home, my father stopped me   50  smiled. “Do you still want that cartoon book?” he asked. I looked at my “foolish” father and answered loudly, “Father, you are the greatest!”
