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!”
