Piers had made it out a good ways before he decided to just tread water and float about for a bit. After all, he didn't want to exhaust his muscles and end up regretting the swim. Although, he trained on a regular basis that he knew when to return to shore. As he swam, he noticed a surfer wave at him.
At first, he glanced around to make sure that the guy was actually waving at him, and given that there wasn't anyone in the immediate vicinity, Piers gave a wave back. He didn't recognize the other make but he saw no reason to not return the gesture. Hell, maybe Piers would ask the guy for information on surfing trainers. He pondered over the idea, making sure to not stare at the surfer as he did so.
