When I was young, my father had one of the first telephones in our neighborhood. I remember the shiny box on the wall. But I was too little to reach it, I could only listen to my mother talk on it. I discovered that inside the wonderful box lived an amazing person whose name was Information Please. There was nothing she did not know. One day my mother went out. I accidentally hurt my finger when I was playing with a hammer. I walked around the house sucking my hurting finger, finally seeing the telephone. Quickly I dragged a chair over and climbed up.

"Well, Sally left a message for you. The note said, "Tell him I still say there are other worlds to sing in. He'll know what I mean." I thanked her and hung up. I knew what Sally meant.
