The Riptide

Kalani had promised her mother that she wouldn't go in the sea. It was the May holiday, the beach was crowded, and a red flag was flying near the water. The red flag meant that the sea was dangerous and nobody should swim. So at three o'clock she was sitting on her towel, reading, while the waves crashed noisily a few meters away. The lifeguard's tower stood at the far end of the beach.

She noticed the man because he was the only swimmer in the water. He was older, maybe sixty, with a white swimming cap, and he was swimming strongly toward the beach. But he wasn't getting any closer. Every time she looked up from her book, he was a little farther away.

Then she noticed the water around him. On both sides of him, the waves were breaking white. In front of him, there was a strip of darker, flatter water moving out to sea, like a river. She had seen a drawing of exactly this on a sign at the beach entrance, with big red letters: RIP CURRENT. DON'T FIGHT IT. SWIM PARALLEL TO THE SHORE.

The man was fighting it. He was swimming hard, straight toward the beach, and his arms were getting slower and slower. If he kept doing that, he wouldn't have the strength to reach the shore.

Kalani jumped up and ran to the edge of the water. Her first thought was to swim out to him, but then she remembered the smaller words at the bottom of the sign: DON'T SWIM OUT. THROW SOMETHING THAT FLOATS. A boy nearby was holding a bright yellow bodyboard. "Get the lifeguard!" she told him, and she grabbed the board as he ran off. Then she waded in up to her knees.

"Don't swim to the beach! Swim sideways, that way!" she shouted as loudly as she could, pointing along the shore. Then she pushed the board into the dark strip of water. The same current that was pulling the man out to sea carried the board straight to him.

He grabbed the board and held on. Then, slowly, he began kicking sideways, parallel to the beach. After about twenty meters, he was out of the dark water. Then the waves pushed him toward the shore, and a few minutes later he was crawling onto the sand, coughing. The lifeguard arrived, running, with the boy behind him.

The man's name was Mr. Delacroix. "I've swum at this beach every holiday for forty years," he said, still breathing hard, "and today a teenager had to teach me how."

That evening, Kalani found the summer lifeguard course online, and before she went to bed, she had filled in the form. Her mother, reading over her shoulder, didn't say a single word about promises.
