One day, a man was brushing his front wall. A boy saw him nd ran up. "Why do you want to brush that wall white?" "Cause it makes the wall look beautiful," said the man. Then the boy had a bad idea. "I can get some rocks and hit the wall so that the man couldn't paint his wall," he thought in his head. So he ran off. And he came back with a big rock inside his arms. "What are you doing?" shouted the man. "Stop it!" But the boy didn't listen. He hit the wall hard with the rock. The wall cracked. Oh no!
