When he passed three streets, he saw an old woman sitting in the park and watching some birds. She looked very hungry. The boy gave her a pizza. She took it and smiled at him. The smile was so beautiful that he wanted to see it again, so he gave her a Coke. She smiled once again. The boy was very happy. They sat there all the afternoon, eating and smiling, but they said nothing. When it grew dark, the boy decided to leave. But before he had gone more than a few steps, he turned around, ran back to the old woman and gave her a hug. The woman gave him her biggest smile ever. When the boy opened the door of his house, his mother was surprised by the look of joy on his face and asked what had made him so happy. "I had lunch with Love. She has got the most beautiful smile in the world." At the same time, the old woman,s son was also surprised at his mother,s pleasure and asked why.
