There was a little boy called Peter. He lived in a village close to the sea. The villagers built seawalls to keep sea water from the doors of the houses. But once the sea walls almost put the village in great danger.
One day, Peter was walking on his way back home along the sea wall when it began to rain. All of a sudden, he saw a hole in the wall, from which the sea water was running.
Peter shouted for help because he knew the hole meant that the sea was making its way through the sea wall, but no answer came. He realized he should do something else as quickly as possible, of the sea water could be pouring over the whole village. He started to rush towards his village.
At the same time, the rain became heavier and heavier.
It was getting dark, but Peter rushed on and on. He felt cold and hungry in the rainstorm, he fell down over and over again. Many times he thought about giving up, but he fought on.
He remembered his father's words, "Lots of strong men have made every effort to build the walls which can keep the village safe from danger.
The sea walls are really important. "Finally, when the boy's father saw him. Peter had been black and blue all over. The boy told the villagers what had happened to the sea wall. They repaired it in time. "Thank God! He saved the village." They praised Peter. All the villagers called him "Peter the Guard" from then on. Peter's parents were really proud of him!
