“Who did this?”asked Miss Green.

There were 30 children in the classroom and all were trying to think about not only what they did, but also what our teacher already knew.

“Who broke this window?” 

“Uh, Oh.”I thought. I was the one who broke the window with a football. I did not mean to do it. I would be in a lot of trouble. How could I pay for a big window like that? Ididn't want to put up my hand. But I had to tell the truth. So, I put up my hand and told the teacher I broke the window.

Miss Green went to the bookshelf and took down a book.

“I know how you like birds, Peter.”She said .“Here is a book about birds and the book is yours now. I will not punish you this time. But Peter, you should remember that I am rewarding (奖赏)you for your honesty(诚实), not for breaking the window.”

I couldn't believe it! The teacher didn't punish me and I was getting my very favorite book. Now, I still use that book, and it always reminds me of (使我想起)the lesson my teacher taught me.

Honesty is always best.
