Dawson was an angry old man，and everyone knew it. He had the best apples in town，but kids knew they couldn't go into his garden to pick apples because he would run after them.
One Friday，12-year-old Janet was going to stay all night with her friend Amy. They had to walk by Dawson's house on the way to Amy's house. As they got close，Janet saw him sitting in front of his door. So she suggested （建议）they should cross over to the other side of the street. Like most children，Janet was afraid of him.
Amy said Dawson wouldn't hurt them and kept walking. When they got closer，Dawson looked up angrily. But when he saw Amy，he smiled and said， "Hello，Amy. I see you've got a friend with you today. "
Amy smiled back and told him Janet was staying overnight and that they were going to play games. Dawson said that sounded fun and gave them each a fresh apple.
They walked on for a while，and then Janet asked Amy， "Everyone says he's not friendly.
Why was he so nice to us ?"
Amy said， "When I first walked past his house，he wasn't friendly and I was afraid of him. But I pretended（假装）he was wearing an invisible（看不见的）smile and so I smiled back at him. It took a while，but one day he smiled back at me. "
"An invisible smile?" asked Janet.
"Yes，" answered Amy， "my grandma told me that if I pretended he was smiling an invisible smile at me and I smiled back at him，then sooner or later he would really smile. "
