One day you go to the beach. It is a splendid day. The sun is shining. The sand is white as can be. The sky is blue. You are in a great mood. Suddenly, you see a lifeguard run into the water and begin swimming at a furious pace. In the distance, you see a person drowning. It is a terrible sight to see. The good news is that the lifeguard is up to the task of saving the person’s life. The individual who was drowning is saved. Thank goodness!
