She was lying on the beach. It felt really calm. The sun was beaming down. It was not too hot. The weather was perfect. She was lying on her stomach. She was in paradise. Suddenly, something happened. Someone ran by. Sand was kicked on her back. She was startled. She sat up to see who kicked it. There were a lot of people around. She did not see who ran by. She felt angry. Someone had ruined her moment in the sun. She lied back down. Minutes later, someone ran by again. Sand was kicked on her back. She rose instantly. She saw a kid hiding. He was laughing. She stood up and walked towards the kid. "Were you kicking sand on my back?" she asked the kid. The kid was scared. He started crying. She felt guilty for making him cry. "Don't cry," she said. "I'm sorry," the kid said. She never came back to that beach again.
