Once a rich businessman gave his daughter a beautiful necklace. But later the necklace for the girl went missing. The businessman offered a reward of $50,000 for anyone who could find it.
One day Robin was walking home along a dirty river. He saw something shining in the river. It was the diamond necklace! He decided to catch it so that he could get the reward.
He put his hand in the dirty river and tried to catch the necklace, but somehow missed it.
He tried again. This time he walked into the river and put his whole arm in to catch the necklace. But strangely, he still missed it!
He came out and started walking away. Then again he saw the necklace, right there. He decided to give it a final try.
He jumped into the dirty water and searched everywhere for the necklace but still he failed. He came out feeling very sad.
Just then an old man, who was walking by, saw him and asked what was wrong. At first Robin did not want to share the secret with the old man. But finally he decided to tell the truth.
He told the old man about the necklace and how he tried to catch it. The old man then said, "Perhaps you should try looking up, towards the branches(枝条)of the tree, instead of in the dirty river.
Robin looked up and the necklace was indeed on a branch of the tree. He had tried to catch a reflection(倒影)of the real necklace all the time.
