One day, two good friends,Peter and Bill,were walking through the desert(沙漠) .They
both felt bored and tired because of the long journey.So they stopped to have a good rest.Later,
they began to quarrel and Peter slapped(打耳光)Bill in the face.But Bill didn’t say anything to
hurt Peter.He just wrote ten words in the sand,“TODAY,MY BEST FRIEND PETER SLAPPED ME IN THE FACE.”
Soon they went on walking until they found an oasis(绿洲)in the desert. They decided to take a bath in the lake.Bill jumped into the lake fast.Maybe he was too tired to go up.He was dropping under the lake.Just then,Peter quickly jumped into the lake and pulled him out of water.Peter saved Bill’s life! Again Bill wrote ten words on a stone instead:“TODAY MY BEST FRIEND PETER SAVED MY LIFE IN HERE.”
Peter was surprised to see that and asked,“Why did you write in the sand after I hurt you and wrote on a stone now?”
Bill smiles,“The words in the sand are easy to miss,but the words on the stone may be there always.”
