In this story, who or what is Sue in conflict with?
A boy in a green shirt yelled, "I can't find my sister. She went underwater right there, and she never came up!"
As a lifeguard, Sue knew exactly what to do. Racing into the ocean, she leaped and crashed through the waves. Sue swam to the spot where the boy had pointed. Taking a deep breath, she dove to the bottom, opened her eyes, and began searching everywhere. As she surfaced, a wave buried her and shoved her under again.
When Sue finally resurfaced, she saw a crowd of people on shore. "Here she is!" they called.
Sue saw a girl standing in the sand, calmly eating a sandwich. Her little brother had gone back to his sand castle.
