One day, a little girl named Lily went to the park. She saw her friend Tom playing with a ball. Tom looked sad and had a frown on his face. Lily asked, "Tom, why are you sad?"
Tom said, "I lost my heart necklace. My mom gave it to me. It is very special." Lily wanted to help Tom find his necklace. They looked and looked, but they could not find it. They were both very sad.
Just then, a small bird flew down and landed near them. The bird had something shiny in its beak. It was Tom's heart necklace! The bird dropped the necklace in Tom's hand. Tom and Lily were so happy and surprised. Tom's frown turned into a big smile. They thanked the bird and played in the park all day.
