After forty-three years I have forgotten the name of the old lady, who was a   16   on the newspaper route in my hometown when I was a twelve-year-old boy. Yet it remains in my memory that she taught me a lesson in     17   that I shall never forget.

I found a   19   smooth rock and threw it out, but it  20  straight not for the roof but for a small window of the old lady’s house.   21   the sound of broken glass, we knew we were in trouble. We ran faster than any of our   22    flew off her roof.
I was so   23   about getting caught that first night   24   I was not concerned about the old lady with the broken window in winter.    25  , a few days later I started to feel guilty for her misfortune. She    26   greeted me with a smile when I gave her the newspaper, but I was no longer able to act    27   in her presence.
I    28   my mind that I would save my newspaper delivery money, and in three weeks I had seven dollars. I put the money in an envelop with a    29   explaining that I was sorry for breaking her window and hope that the seven dollars would    30   the cost for repairing it.

The next day, I handed the old lady her newspaper. She thanked me and gave me a bag of cookies she had made herself.   34  eating cookies, I felt an envelope and pulled it out of the bag. After opening it, I was shocked. Inside were the seven dollars and a short note    35  , “I’m proud of you.”
