This happened to me at the age of twelve. It seems like a long time to remember the name of the old lady. Yet it keeps in my  35 that she taught me a lesson in tolerance(宽容) which I shall never forget.
On a winter afternoon, a friend and I were  36 stones onto the roof of the old lady’s house. I found myself a perfectly smooth stone and threw it out. The stone was too smooth, however, so it slipped(滑) from my hands and  37  straight not for the roof but for a small window on the old lady’s back porch(门廊). At the sound of broken   38 , we knew we were in trouble and ran away.
I was too scared(胆怯) about getting caught by the old lady that first night. However, a few days later, when I was sure that I hadn’t been   39 , I started to feel guilty(有罪的) for what I had done. She  40 greeted me with a smile each day when I gave her the newspaper, but I was no longer able to act comfortably.
I made up my mind to  41 for her window with my paper delivery(发送) money I collected. I put the money in an envelope with a note explaining I was  42  for breaking her window and hoped that the seven dollars would cover the cost for repairing it.
I waited  43 it was dark, snuck(悄悄地走) up to the old lady’s house and put the letter I didn’t sign in her door. Once again, I could have the freedom of lookingstraight  44 the old lady’s kind eyes.
The next day, I handed the old lady her paper and was able to return the warm smile that I was  45 from her. She thanked me and gave me a bag of cookies.
Reaching for the cookies, I  46 an envelope and pulled it out of the bag. When I opened the envelope, I was surprised to see the seven dollars and a short note that said, “I’m proud of you!”

I have forgotten the name of the old lady, who was a customer(顾客) on my newspaper route when I was twelve. Yet she taught me a lesson that I shall never forget.

On a winter afternoon, a friend and I were throwing stones onto the roof of the old lady’s house near her garden. I found myself a perfectly smooth rock and threw it. The stone was too smooth, however, so it slipped(滑) from my hand as I let it go and headed straight for a small window on the lady’s door. At the sound of broken glass, we knew we were in trouble. We ran faster than any of our stones flew off her roof.

I was too scared about getting caught that first night to be concerned about the old lady with the broken window in winter. However, a few days later, when I was sure that I hadn’t been discovered, I started to feel guilty for her trouble. She still greeted me with a smile each day when I gave her the newspaper, but I was no longer able to act comfortably when seeing her.

I decided that I would save my paper delivery(送) money, and in three weeks I had the seven dollars that I thought would cover the cost of her window. I put the money in an envelope (信封) with a note saying that I was sorry for breaking her window and hoped that the seven dollars would cover the cost of repairing it.

The next day, I handed the old lady her paper. She thanked me for the paper and gave me a bag of biscuits she had made herself. I thanked her and ate the biscuits as I continued my route.

After several biscuits, I felt an envelope and pulled it out of the bag. When I opened the envelope, I was shocked. Inside were the seven dollars and a short note that said, “I’m proud of you.”
