Footsteps! Someone was coming. Jon could't see where that someone was coming from but he knew that he was in trouble. Not just that he was wearing a girl's one-piece swimsuit, he was also trespassing at the pool. He had to get away!
He tried to make as little sound as possible as he was moving to the edge of the pool. As he pulled himself up out of the water, he must've splashed around too much because a voice called out immediately.
“Who is there? Show yourself!“ the voice shouted. Jon could still not see the person but the footfalls he heard were getting louder and faster. He looked around for the nearest object that could hide him and scrambled for it. It turned out to be a decorative hedge.
Jon risked a peek over the hedge and saw who had heard him. It was a young man in a red speedo and white t-shirt. A lifeguard making a round before opening the pool.
At least it wasn't the police. Jon crouched behind his hedge, the wet swimsuit clinging tightly to his body and hoped that his hiding spot kept him from being found.
