Jenny was a pretty five-year-old girl. One day when she and her mother were checking out at the grocery store, Jenny saw a plastic pearl (珍珠) necklace priced at $2.50. Her mother bought the necklace for her on condition that she had to do some homework to pay it off. Jenny agreed. She worked very hard every day, and soon Jenny paid off the necklace. Jenny loved it so much that she wore it everywhere except when she was in the shower. Her mother had told her it would turn her neck green!

Jenny had a very loving daddy. When Jenny went to bed, he would read Jenny her favorite story.

One night when he finished the story, he said, “Jenny, could you give me your necklace?”

“Oh! Daddy, not my necklace!” Jenny said. “But you can have Rosy, my favorite doll. Remember her? You gave her to me last year for my birthday. Okay? ”

“Oh no, darling, that’s okay.” Her father brushed her cheek with a kiss. “Good night, little one.

A week later, her father once again asked Jenny for the necklace after her favorite story. “Oh, Daddy, not my necklace! But you can have Ribbons, my toy horse. Do you remember her? She’s my favorite.”

“No, that’s okay,” her father said and brushed her cheek again with a kiss. “God bless you, little one. Sweet dreams. ”

Several days later, when Jenny’s father came in to read her a story, Jenny was sitting on her bed and her lip was trembling. “Here, Daddy,” she said, holding out her hand. She opened it and her beloved pearl necklace was inside. She let it slip into her father’s hand.

With one hand her father held the plastic pearl necklace and with the other he pulled out of his pocket a blue box. Inside the box was a real, beautiful pearl necklace. He had had it all along. He was waiting for Jenny to give up the cheap necklace so he could give her a real one.
