"What isit?" I wondered. I turned it over. There, in faded ink, was a hand-written address. Immediately my mind traveled many years back.     I was nine years old, walking down the cold and wet streets of Springfield, with a bag of magazines on my shoulder. That day, I came to the company finally, whose owner, Mr Rader, had always taken me thereto ask his workers if they wanted any magazines.      Shaking off the rain like a wet dog, I went into Mr Rader's office. After a quick look he took me over tothe fireplace. Noticing the hole in the top of my shoe, he said, "Come with me!" and pulled me into his car. We stopped in front of a shoe store. Inside, a salesman fitted me with the finest pair of shoes I had ever seen.I felt about 10 feet tall when I got up in them. "We'd like a pair of new socks, too." Mr Rader said.      Back in his office, Mr Rader took out a card, wrote something on it and handed it to me. With tearful eyes, I read, "Do to others as you would have them do to you." He said kindly, "Jimmy, I want you to knowI love you."      I said good-bye, and for the first time I sensed a piece of hope that things would be better. With people like Mr Rader in the world, there was hope, kindness and love, and that would always make a difference. 1. The writer went to Queen City Casket Company to ______.
